Title: SINE WAVE MULTIPLIER DEVICE AND INPUT DEVICE COMPRISING SAME
Abstract:
Signal components in an output signal Qu1, namely a signal component corresponding to the product of an input signal Vi and the third harmonic of a first rectangular wave W1 and a signal component corresponding to the product of the input signal Vi and the fifth harmonic of the first rectangular wave W1, are canceled out by a signal component in an output signal Qu2, namely a signal component corresponding to the product of the input signal Vi and the fundamental of a second rectangular wave W2, and a signal component in an output signal Qu3, namely a signal component corresponding to the product of the input signal Vi and the fundamental of a second rectangular wave W3.
