Hi everyone,
I am planning to implement a circuit which could demonstrate the working of PAM-TDM.
The inputs are two speech signals.I want to have 16KHz as the sampling frequency.I need to generate two such generators with some phase difference between them.The time period corresponding to 16KHz will be 62.5µs.The pulse width of 12.5µs would do the job.
The signals are shown in the attached document.I have performed the simulation of the circuit using multisim and it gives satisfactory response.
Any ideas on how to generate the pulse generators with 12.5µs delay between pulses?
I can use 555 to generate two different pulse generator or I can even use the function generators available in the lab.The main issue is how to get the desired time delay.
