Frequency shift keying (FSK) square wave generator with CD4046B

Published:2013/1/28 2:11:00 Author:Ecco | Keyword: Frequency shift , keying, FSK, square wave generator

Frequency shift keying (FSK) square wave generator with CD4046B
The keying signal is applied to control input end-pin 9 of CD4046, when the keying input is 1 level, the circuit will generate 2.4kHz audio frequency; when the input is 0 level, it will generate l.2kHz audio frequency. High - frequency tones are preset by the component values of Cl and Rl, and low-frequency tones is preset by the value of Cl, R2 and R3. (View)
