# 6.2 M-ary Amplitude Shift Keying (M-ary ASK)

## Implementation of M-ary ASK

#### Extending binary ASK to multi-level ASK is a simple concept, and the generation and detection process scales up to requiring multi-level comparison of the recovered envelope signal for either coherent or non-coherent detection.

#### Carrier recovery for M-ary ASK is performed with the same methods as employed with binary ASK.
