ABSTRACT:
A signal envelope measurement preprocessing circuit including: input signal adjuster for interdicting a DC component contained in a signal input for measurement of the degree of flatness of an envelope or for passing only frequencies above a predetermined frequency; first and second half-wave rectifiers for separating into upper and lower portions the envelope of a signal output from the input signal adjusting means to thereafter detect the same; first and second frequency converters for converting a high frequency signal respectively from the first and second half-wave rectifiers into a low frequency signal; an analog-to-digital converters for converting a signal selected from low frequency signals output from the first and second frequency converters to a digital signal; and a system controller for comparing a data output from the analog-to-digital converter with a data stored on an internal program to thereafter measure the degree of flatness of a signal envelope.
