Abstract
An amplitude limiting circuit is provided in which the input signal is fed to the non-inverting input terminal and the output is taken from the inverting input terminal of an operational amplifier having a feedback resistor connecting the inverting and output terminals of the amplifier. Either the input resistor, feedback resistor or operational amplifier supply voltages can be used to alter the upper and lower limit voltages of the circuit.
