Hi all,
I have an existing RC network in a digital circuit to delay a certain signal by ~70ns. The resistor value is 10R and the capacitor's is 680pF.
The delay does its job, although I know there are better ways to delay digital signals but anyway that is not an option right now.
I would like to be able to switch this delay network in and out of circuit with a mechanical switch but I have found that if I add any additional wiring the circuit no longer works. I understand the wiring will add capacitance and resistance but I didn't expect this to have that much influence; beginner here obviously, I must be violating some fundamental principles :-)
Would changing the combination of R an C help in this?
Your help and expertise is much appreciated,
John
