Mark and space frequencies
Mark and space communication frequencies are defined by the following formula:
F ("0") = FCarrier + [∆F]/2
F ("1") = FCarrier - [∆F]/2
∆F is the Frequency Deviation.
With Deviation = “0.5” the difference in terms of frequency between the mark and space
tones is half the Baudrate value (
∆F = 0.5*BAudrate). When the Deviation = “1” the
difference is the Baudrate itself (
∆F = Baudrate). The minimal Frequency Deviation is
600Hz.
