摘要: In a modulation system, in order to provide two-level signal with desired which is suited be amplified by switching mode power amplifier, the system may include first constant envelope modulator modulating according control signal, second and combining portion output of said single, pulse-width-modulated signal. The information represented coded signals. invention relates equally corresponding method for generating modulated
