The audio-signal router in this Design Idea can automatically redirect cable connections between the audio equipment and an amplifier/receiver for dubbing or playback purposes without causing ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

The circuit is designed to produce an indicator that will show the peak level of audio signal as it exceeds the prescribed limit. The circuit is designed to produce an indicator that will show the ...
