Hi,
I am trying to phase shift a sinusoidal signal by a small amount (a degree or two), I am aware I could do this with some ADC and microprocessor. However I would like to do it with some simpler analogue electronics, I have been looking at an "all-pass filter", however my signal will have a varying frequency and therfore this will not work as an "all-pass filter" will only work for a certain frequency. Any ideas?
Any help would be much appriciated?
Thanks,
Mark
