This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

There are two groups of classic circuits: those which have served us well in the past, but have been superseded by better designs, and those which are still in use, perhaps with updated components. In ...

If your system's signal processing requirements in-clude peak detection and amplification, consider a simple circuit that will satisfy both needs and save hardware. The single-supply circuit shown in ...

The following circuit improves upon a simple peak detector by using a high frequency op-amp and feedback circuitry. The result is better accuracy and more sensitivity at the input. To view the ...

I recently received an email from a student who needed to design a circuit to detect peaks in a 10-MHz analog signal. His plan was to use an A/D converter sampling at well beyond the Nyquist frequency ...

[Alan’s] friend came to him with a problem. He loved listening to his scanner, but hated the volume differences between stations. Some transmitters would be very low volume, others would nearly blow ...
