ABSTRACT:
A logarithmic attenuating circuit is disclosed for multiplying by a constant factor the logarithmic range of input voltages which can be accomodated by a variety of test equipment. The circuit functions as an amplifier having a gain which varies inversely with the root mean square of the output voltage. The effect of the circuit is to produce from the a.c. component of an input signal, an output signal having the same shape as the input signal but an amplitude of its a.c. component proportional to the n-th of the amplitude of the a.c. components of the input signal.
