Both mark and space have the same
amplitude and at nominal frequencies.
Band limited random noise: 200-3400 Hz.
Present only when FSK signal is present. #
* Twist = 20 |log ( f
H amplitude / fL amplitude )|.
# BT band is 200-3400 Hz, while Bellcore band is 0-4 kHz.
Notes:
dBV = decibels above or below a reference voltage of 1 Vrms.
