摘要
An envelope extracting apparatus includes: a clock extracting device arranged to extract a clock signal of a receiving modulation signal according to a first biasing voltage; and an edge detecting device arranged to generate a detecting signal to indicate an envelope edge of the receiving modulation signal according to a delayed clock signal of the clock signal and a second biasing voltage; wherein the second biasing voltage or a delay time of the clock signal is adjustable.
