A simple stereo tv decoder circuit build with MC1310P. Transistor Q1 is an audio amplifier and U1 is used as a 31.5KHz subcarrier which is similar to 38KHz FM MPX. Pilot frequency is 15.734KHz. Stereo ...

He first built a breadboard decoder circuit that would light 1 of 16 LEDs depending on the detected button press. This was well and good, but he decided that an Arduino-driven LCD display would ...

A voltage-doubler circuit detects the 22-Hz portion, producing a pulse stream in which constant-voltage pulses having amplitudes of 0.6 to 1.2V replace the 22-Hz bursts. Decoding this bit stream into ...

On one end of the twisted pair is a power supply and decoder circuit, which sends 9 volts up the line to power the PIC sensor. The decoder is based on a CD4538 dual monostable multivibrator, set ...

When the film soundtrack is recorded, the surround sound channel is encoded by first filtering it and attenuating it by 3dB, and then passing it to two phase shifting circuits. One of these shifts ...

The resulting circuit, shown in Figure 4, although an approximation to Pa/Pb, matches the variable node operation we require for an err-r correcting decoder.. Figure 3: Stochastic division. The ...

DSC achieves visually lossless compression quality at a low compression ratio by using a much simpler codec (coder/decoder) circuit. The typical compression ratio of DSC range from 1:1 to about 3:1 ...
