Instructions for Frequency Shift Keying (FSK) Demodulation

Step 1: You can Demodulate the FSK Signal clicking on the 'Demodulate FSK' button
Step 2: Click on the 'Generate BER vs SNR' button to plot BER vs SNR graph
Step 3: Click on the 'Generate letellation' button to see the constellation diagram of FSK
Tip: FSK Modulation settings auto-transfer to the FSK Demodulation tab. No need to re-enter values. Keep both tabs open, or demodulate immediately after modulation.
