What is a"harmonic sinewave"?
Is the opamp a lousy old 741 that has poor performance above only 9kHz?
Or is it a modern opamp that works perfectly up to 100kHz?

this is the output file for sinewaveform,and i want it to simulate to show how is the signal pattern.

Normally multiple sections are used to reduce distortion of the resultant sine wave.
ya,im looking for this answer but i dont how should i simulate on th pspice.
because based on my circuit,it is not purely sine waveform,so i want to know how good is this sinewave and my supervisor ask me to perform harmonic on this sinewave generator.im stuck on this harmonic.
