ABSTRACT:
The square root insertion circuit of this invention has an operational amplifier circuit with a multiplying circuit of the voltage-time product type in its negative feedback path. The multiplying circuit is connected so that the time factor is proportional to the amplifier output signal and the voltage factor is also proportional to the amplifier output signal. Thus, the multiplying circuit acts as a squaring circuit to cause the output signal of the amplifier to be directly related to the square root of its input signal.
