Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. Which voltage represents 1 and which represents 0 is left to the system designers. These two phases are 180 degrees apart. Laser transmitters normally have a fixed "bias" current that causes the device to emit a low light level. In amplitude shift keying (ASK), the strength of the signal is varied to represent binary 1 or 0. Because the preamble and header always are sent at a 1-Mb/s rate using binary phase shift keying (BPSK), the dark blue and red triangles occupy only two areas opposite each other.

This low level represents binary 0, while … Frequency-shift keying (FSK) is a method of transmitting digital signals using discrete signals. Suppose you have 9 coins and one of them is heavier than others. However, PSK can be extended to 4 level and 8 level PSK that totally depends on the need of the system. If the message is mapped only to the frequency of the carrier, the modulation is called frequency shift keying or FSK. Why is ASK called on-off keying? The optimum correlation receiver for coherent reception of BPSK is shown in Fig. therefore, it is also known as ONP-FF keying (OOK). In an ASK system, a symbol, representing one or more bits, is sent by transmitting a fixed-amplitude carrier wave at a fixed frequency for a specific time duration.
