P_ED1000_FSK
For signaling Z (logical 1) a high frequency is used (700Hz, 3150Hz). For signaling A (logical 0) a lower frequency is used (500Hz, 2250Hz). Both frequencies have the same amplitude.
In frequency domain ...
For sending a character the transmitter switches between the corresponding frequency with the giver baud rate.
For timing see: Baudot-Murray-Code
