FSK The 98 Series transmitter, the IT-98DSP, generates a FSK audio signal over a voice grade communicatioins channel such as a leased telephone line, microwave, copper pair of wires, or single sideband. The IR-98DSP receiver accepts the audio signal from the transmitter and generates an output.

spectrum several audio FSK signals are often combined for transmission by a single-side-band transmitter. This form of FDM is often called Voice Frequency Telegraph (VFT). To minimize bandwidth, the individual FSK channels usually have “narrow” shifts of between 50 and 200 Hertz. A typical FDM system is shown in Figure 5. HF radio sys-

https://dsp.stackexchange.com/questions/29946/demodulating-fsk-audio-in-python
Show activity on this post. I am trying to write a Python script that can demodulate an FSK modulated audio file and return the data encoded in the audio. The data being transmitted is GPS NMEA strings which are embedded as the audio channel in video files. Basically, text is encoded with FSK modulation, and I am trying to retrieve the text ...
FSK: Signals and Demodulation

FSK Demodulation: WJ Tech Notes 1980 4 Frequency Division Multiplex (FDM) Several FSK signals can be transmitted simultaneously in a given frequency band by assigning different center fre quencies to each of the FSK signals. This metho d of simultaneous trans mission is called FDM. In the radio spectrum several audio FSK

FSK - frequency shift keying D1 - 61 Conceptually, and in fact, the transmitter could consist of two oscillators (on frequencies f1 and f2), with only one being connected to the output at any one time. This is shown in block diagram form in Figure 2 below.
Lab6 Part A- Audio Frequency Shift Keying (AFSK)
https://inst.eecs.berkeley.edu/~ee123/sp15/lab/lab6/Lab6-Part-A-Audio-Frequency-Shift-Keying.html
The exact frequency spectrum of a general FSK signal is difficult to obtain. But, when the mark and space frequency difference Δ f is much larger than the bit-rate, B, then the bandwidth of FSK is approximately 2 Δ f + B. This is not exactly the case for AFSK1200 where the spacing between the frequencies is 1000Hz and the bit-rate is 1200 baud.
