Understanding Frequency Shift Keying (FSK)

FSK is a form of digital modulation where binary data (0s and1s) is presented by disproporte changes in thee frequency of a carrier signal. A classic implementation uses two distrant frequencies: one for a binary indifers; 1eds; (mark frequency) anod anotherr for a binary indigates; 0esti; (space frequency).
