Frequency Shift Keying (FSK) Encoding and Decoding

Posted on Feb 5, 2014

The meaning of Frequency Shift Keying (FSK) is transmitting digital data over a signal path (two wires, telephone lines, AM or FM transmitter). Typically, there are only two signals transmitted. One corresponds to a logical 1 ³. the other to a logical 1 ³. These two frequency will be generated by a TC9400 V/F converter when connected as shown be

low. The V/F converter is set to the lower frequency by the potentiometer. Which frequency is selected is determined by the digital input. A 1 ³ selects the upper frequency and a 0 ³ selects the lower frequency. TC9400, in F/V mode, convert back the digital frequency signal into a digital format.
