幅度键控 Amplitude-shift keying

(重定向自Amplitude Shift Keying)

幅度键控(ASK)是一种通过载波的幅度变化来表示数字信号的幅度调制方式。在一个ASK系统中,二进制符号1会通过一个固定振幅、固定频率的载波信号来表示。这一载波信号会持续T秒。如果信号的值为1,就会传输载波信号,反之则不会传输载波信号。

ASK diagram

Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. In an ASK system, the binary symbol 1 is represented by transmitting a fixed-amplitude carrier wave and fixed frequency for a bit duration of T seconds. If the signal value is 1 then the carrier signal will be transmitted; otherwise, a signal value of 0 will be transmitted.
