Hello all
I have attached a schematic of the Twin T oscillator circuit I'm working on.
When no positive feedback is given, the ckt. seems to corroborate with the oscillation frequency formula given by f = 1 / (2pi RC). This was simulated in Pspice.
Upon giving an addtional positive feedback to the same ckt. the frequency changes. From one of my earlier posts, i got a response saying it was because of saturation being reached upon addition of positive feedback. Is there a way to still calculate the resulting frequency for the different values of resistors in the positive feedback?
Please comment.
