If you use an RC network you'll have : cos teta= R/Z ( series network ) and Z= ((R^2)+(XC^2)) under radical or R+1/jwcif you please give me an example of one stage and related formula then it
Dear Bradtherad,
Thanks for your help.....it really helped me.
if you please give me an example of one stage and related formula then it will be better for me.
I can u will need to square wave it then back to sine
The basic concepts are illustrated below. You can adapt one or more to your purposes. Because these are also passive filters, you may need to find a method that does not reduce your signal amplitude too much.
The formula for capacitive time constant: R * C
The formula for inductive time constant: L / R
An internet search should turn up discussions about how to calculate the phase change caused by a given RC or RL combination.
A 90deg shift is easily possible by using an L & C in parallel, and which are tuned to the exact carrier frequency.
rohitkhanna,
The currents in the L branch and the C branch of a parallel circuit are 180° opposite each other no matter what the voltage frequency is.
