Amplitude-shift keying (ASK) is a form of modulation that ...

Most common is binary FSK (BFSK), where one amplitude is represented by a carrier frequency f. 1 while the other logic level is represented by carrier frequency f 2. (fig 1). FSK is less susceptible to noise than ASK.Fig 1. An FSK signal V. FSK. It is possible to convert signals to the amplitude shift keyed signal by the use of a Selector Switch. ................
