Abstract

PURPOSE:To cancel phase change dependent upon frequency change, by inserting a circuit having a group delay time to the transmission line between the input and the output and by providing a frequency detector and a variable phase shifter for change of the frequency of the signal given to the input. CONSTITUTION:Circuit 10 having group delay time gammad is connected between the input and the output, and the signal generated in circuit 10 is supplied to not only output-side variable phase shifter 60 but also frequency detector 70, and the frequency of the input is detected, and the output voltage is supplied to phase shifter 60 to change the phase of the signal passing through circuit 10 according to the output voltage. In this constitution, if characteristics of detector 70 and phase shifter 60 are set to desired those, phase change becomes 0, and the phase relation between the input and the output is not changed even for change of the frequency of the input. Consequently, a desired output delayed by gammad can be obtained with a simple circuit.
