Hi All
My input signal is a varying duty cycle pulse (sign wave modulated) the frequency is fixed 26KHz. How I can change the frequency of the input signal +/-2KHz (24KHz to 28KHz) basically I would like to change the frequency of the input signal so that the emission is spread across the spectrum. I have implemented one circuit with d-flip flops an AND gates, but this approach is complex and more logic devices need to be used. Can anyone suggest simple logic circuit to implement this functions. Attached the circuit, using this circuit I can substract the single pulse from the input signal.
Thanks
