Low Power Amplifier with digital volume control

Amplifier with digital volume control can we make predictably because the circuit is made simple with just single chip TDA8551. The series of Mini Amplifier With Digital Volume Control is a type BTL amplifier with 1 Watt.Techniques for adjusting the volume in this series has been provided with a pin path control that is controlled by providing an input voltage VCC and GND. The series is also

Low Power FM Transmitter

This
article should satisfy those who might want to build a low power FM
transmitter. It is designed to use an input from another sound source
(such as a guitar or microphone), and transmits on the commercial FM
band - it is actually quite powerful, so make sure that you dont use it
to transmit anything sensitive - it could easily be picked up from
several hundred metres away. The

Multiplexer with Limiter and Low Pass Filter

This is a design circuit for stereo encoder. This circuit is using BH1417 Stereo Encoder. This circuit using with pre-emphasis, limiter so that the music can be transmitted at the same audio level, low pass filter that blocks any audio signals above 15 KHz to prevent any RF interference and crystal based stereo encoder for stereo transmission. This is the figure of the circuit.The BH1417 single
