Abstract
A signal generation circuit includes a limiter and a mixer. The limiter receives an input signal, allows the input signal to be off a scale at a limit voltage, and generates a phase signal indicating a phase component of the input signal. The mixer receives the input signal and the phase signal, and generates an amplitude signal indicating an amplitude component of the input signal.
