STEREO MIXER circuit | Next Electronics

The total gain of the car antenna amplifier is approximately 30 dB, with an input impedance of around 10 kΩ at 30 MHz. The amplifier should be mounted directly at the base of the antenna to prevent signal losses attributed...

Amplifier circuit

An amplifier is a device that accepts a varying input signal and produces an output signal that varies in the same way as the input but has a larger amplitude. The input signal may be a current, voltage, mechanical motion,...

Stereo channel controller

The add-on circuit presented here is useful for stereo systems. This circuit has provision for connecting stereo outputs from four different sources/channels as inputs and only one of them is selected/connected to the output at any one time. When power...
