    摘要: A signal measurement apparatus and signal measurement method are provided. The measurement apparatus includes a compensation signal generating circuit configured to generate a target compensation signal that reduces a carrier frequency component in a voltage signal that is input into an amplifier based on an output signal of the amplifier, and the amplifier amplifies the voltage signal to which the target compensation signal is applied, wherein the compensation signal generating circuit is configured to determine a signal value of a subsequent compensation signal based on a signal value of the output signal of the amplifier amplified by applying a previous compensation signal, when determining the target compensation signal.
