Abstract
A multiplier 3 multiplies a square wave signal A(ω,t) by a low frequency component signal L(ω,t) to generate an even-order harmonic component signal B(ω,t). A multiplier 4 multiplies the even-order harmonic component signal B(ω,t) by the low frequency component signal L(ω,t) to generate an odd-order harmonic component signal C(ω,t). An adder 5 adds the even-order harmonic component signal B(ω,t) and the odd-order harmonic component signal C(ω,t) to generate the harmonic component signal D(ω,t).
