Figure 17-3: Symbol stream of a 2ASK signal
● "Modulation Depth" (ASK): Shows the modulation depth of the signal (see
"Modulation depth and modulation index" on page 162 for more information).

●
"Modulation Deviation" (FSK): Shows the frequency shift of the signal. The fre-
quency shift (or frequency deviation) is the frequency difference between the
mark (binary 1) and space (binary 0) frequencies representing the binary digits.
