摘要：
A variable delay equalizer comprises two directional couplers, each having a pair of input terminals and a pair of output terminals. A pair of variable phase shifters are inserted respectively between the output terminals of the first coupler and the input terminals of the second coupler. A third variable phase shifter is connected between the second output terminal of the second coupler and the second input terminal of the first coupler. This equalizer makes it possible to shift the peak delay frequency as well as to change the value of the peak delay itself.
