A few years ago, I made several DSP radio consisting of wrapping wires and universal circuit board as shown in the left side of the picture. In those days I did not use Eagle or some cad soft, just I made I want. It is still surely working but I did not make notes of schematic indeed it has gravity sensor, RTC and DSP radio and I myself don't remember the details and this time I make it a bit smarter form.

This is the whole schematic. In all cases, battery problem is a headache. When I use radio at bed-side mostly before sleepbattery shortage is quite annoying me and I love rechargeable one, so I put Lipo charging circuit.

Now it is on sale at tindie. If you have some interest, please don't miss it! The initial one surely receives from lower frequency to FM broadcast, but some points are pointed-out by great customer.

Rating voltage of KT is 3. In my experience, KT can work around that voltage but I surely need to use low voltage drop regulator.When you subscribe, you receive only messages for the product you have subscribed to.

Used the last couple of years a later model, the year it was discontinued. As compared to my brand new modern day FTDX I always go to the "large" DSP for ease of use and Watts really makes a difference. I wanted a for a log time after using my against it at my friends shack. I love mybut have to say the receive is better and quieter on the side by side.

Page Frequency Setting n When first applying power B e f o r e f i r s t a p p l y i n g p o w e rm a k e s u r e a l l connections required for your system are complete by referring to Chapter 3. You can call up a desired frequency to the VFO with the keypad or the memory transfer function see p. Note: Even if you select the ham band, you can set the transceiver to the general coverage frequency. Page 20 The noise reduction function reduces noise components and picks out desired signals which are buried in noise.

The filter selection is automatically memorized in each mode. Page Filter Setting n Filter setting When an optional filter is installed, set the optional filters in initial set mode. Optional filters are not selected by default. Once the tuner matches an antenna, the variable capacitor angles are memorized as a preset point for each frequency range kHz steps.

Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized point. Both keying speed and weight the ratio of dot : space : dash can be set in quick set mode. Page Memory Operation n Memory channels The transceiver has memory channels.

The memory mode is very useful for quickly changing to often-used frequencies. Page Frequency Transferring n Frequency transferring The frequency and operating mode in a memory channel can be transferred to the VFO. Page Set Mode General Set mode is used for programming infrequently changed values or conditions of functions.

The IC has 2 separate set modes: quick set mode and initial set mode. The RF output power can be adjusted from L, 1 to 99 and H for indication, however, it can be adjusted continuously. Note that while adjusting the output power, the power meter is displayed automatically.The Belka-DSP radio receiver is designed to receive radio stations with amplitude, frequency and single-band modulation, as well as telegraph signals at short waves in the frequency range 3.

One of the main features of the radio receiver is its small size — 85x50x20 mm in body and low weight — about g. This makes it very convenient in traveling conditions. Also, high sensitivity is realized when receiving on a complete telescopic antenna. It is possible to adjust the frequency band both from above, from 2. In telegraph mode, the frequency band is constant, about Hz, and its center is regulated from Hz to 1 kHz. The settings of the favorite radio stations can be stored in any of 32 memory locations.

The receiver does not have a built-in speaker, but there is a rather powerful VLF bridge that provides sufficient volume when working with an external speaker, speaker or headphones. The built-in LI-Ion battery lasts for 24 hours of total operating time on the headphones. In addition to the built-in battery, the receiver can also work from an external DC voltage source of 5 V.

The following document describes the basic concepts of Digital Signal Processing DSP and also contains a variety of Recommended Reading links for more in-depth information. Digital Signal Processors DSP take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them.

A DSP is designed for performing mathematical functions like "add", "subtract", "multiply" and "divide" very quickly.

Signals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be of use. In the real-world, analog products detect signals such as sound, light, temperature or pressure and manipulate them. Converters such as an Analog-to-Digital converter then take the real-world signal and turn it into the digital format of 1's and 0's.

From here, the DSP takes over by capturing the digitized information and processing it.

It then feeds the digitized information back for use in the real world. It does this in one of two ways, either digitally or in an analog format by going through a Digital-to-Analog converter. All of this occurs at very high speeds. During the recording phase, analog audio is input through a receiver or other source. This analog signal is then converted to a digital signal by an analog-to-digital converter and passed to the DSP.

During the playback phase, the file is taken from memory, decoded by the DSP and then converted back to an analog signal through the digital-to-analog converter so it can be output through the speaker system. In a more complex example, the DSP would perform other functions such as volume control, equalization and user interface. A DSP's information can be used by a computer to control such things as security, telephone, home theater systems, and video compression.

Signals may be compressed so that they can be transmitted quickly and more efficiently from one place to another e. Signals may also be enhanced or manipulated to improve their quality or provide information that is not sensed by humans e.

Although real-world signals can be processed in their analog form, processing signals digitally provides the advantages of high speed and accuracy.

Because it's programmable, a DSP can be used in a wide variety of applications. You can create your own software or use software provided by ADI and its third parties to design a DSP solution for an application. Digital Signal Processing is a complex subject that can overwhelm even the most experienced DSP professionals. Although we have provided a general overview, Analog Devices offers the following resources that contain more extensive information about Digital Signal Processing:.
