ABSTRACT:
A limiter for limiting an input signal includes a first clamping circuit for clamping the input signal at a first level so that the input signal cannot rise substantially above such first level, a second clamping circuit for clamping the input signal at a second level less than the first level so that the input signal cannot drop substantially below such second level and a single operational amplifier having an input which receives the clamped input signal and an output at which is developed an output signal that is a scaled version of the clamped input signal. The limiter may be used as either a static or dynamic limiter, is simple in design, inexpensive, and can be used in a wide variety of applications.
