Summed up briefly, a peak program meter indicates the level of an audio signal. And, a true peak program meter displays the peak level of the signal waveform no matter how brief its duration. Enough ...

This circuit is useful to detect microwave (gigahertz signal) sources like microwave oven, satellite communication devices, Mobile phones etc. It gives audio visual indications when it detects the ...

The reversal of the current directions in audio circuit elements causes polarity inversion of the acquired audio signal with respect to the reference input signal. The objective of the work presented ...

The diode bias current is created by a transistor-based peak detector circuit driven off the main audio signal. But don’t just take our word for it, watch the video after the break.

The sCODa96-H1-LB-IO-VD.01 audio converter uses pre-configured deep-sleep and sleep modes to facilitate the programming of the driver and reduce overall consumption. In deep-sleep mode, the ...

This paper introduces a novel lock-in amplifier circuit designed for extracting weak sensing signals in noisy environments. The circuit employs two orthogonal vector reference signals, which are ...
