| Abstract: | This paper explains the principle on how to use CD4046 phase locked loop to realize signal frequency MODEM circuit in serial digital communication and how to use Schmidt circuit to reform the demodulated waveform and recover the digital signals. These circuits can be used to communicate between different computers or to detect signals. |
