This file type includes high resolution graphics and schematics. Front-end limiter circuits using Schottky and PIN diodes can provide needed protection in communications and other RF systems. However, ...

This audio limiter circuit is easy to build, works with BA741 8pins or 4pins so pay attention and uses a symmetrical power supply. When the audio input level is between 20mV and 20V the output will be ...

This mini audio compressor circuit use only one active component T1. The audio signal goes thru C1, R1, D1, C2, R3. Still a part of audio signal charge the D3/D4 detector and creates a control voltage ...

[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 ...
