Newbie level 3
I did in two procedures but i am not sure which method is right!
My question is like
Circuit designed as sine wave generator,
to produce Vo with an amplitude of 8.5V at f= 1 kHz. The low-pass filter has been designed to have a low-frequency gain of -1 and a cutoff frequency of 1.5kH
so i need magnitude of the undesired frequency component in output waveform at 3 kHz
I think Ckt has Low pass filter, integrator.
1st method: I have taken transfer function of low pass filter
and solved by replacing R6/R5 by gain -1
2nd method: As integrator produces triangular wave
i used triangular wave transfer function
