Can you provide the circuit diagram

Transmit two signals of frequencies 1 kHz and 2 kHz through a PCM system using multiplexing technique.
 
Simple textbook method to pass or halt a digital signal...
Plain AND gate: Pull one input high when you wish to pass the other input.

Add a second gating system if you need to choose either of two signals.
