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 ...

The limiter was built on a 30-mil thick FR-4 printed-circuit board (PCB) with a 50-Ω co-planar waveguide, with grounded coplanar waveguide (CPWG) transmission line having a gap in the middle .

Contributing editor, Bob Pease, explains how to design several different circuits for limiting currents as high as 300 mA using an LM317, LM334N, IRF640 or IRF740.

Most oscillator circuits include a nonlinear amplitude control that sustains oscillations at a desired amplitude with minimum output distortion. One approach uses the output sinusoid's amplitude to ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...

The controversy behind lower power measurements of receivers implementing limiter circuits reviewed in many magazines is often too familiar but never truly explained. The best way to understand this ...
