Hi guys,
Hope you can help, ive got an assignment question im stuck on and im not sure if its my understanding or my maths skills letting me down! Im guessing from the equation below the soloution will be the fundamental frequency at a certain voltage i.e Vin*98, plus a harmonic of (2/k)*Vi) would that be right? Just need a poke in the right direction! cheers in advance guys
A voltage amplifier ideally should have the input-output relationship of
vo = 100vi but in practice the relationship is;
Vout= Vin (98+((2/k)*Vi)
where k = 1 × 103 V.
(a) Determine the expression for the output voltage when a 10 mV
(peak), 800 Hz, sinusoidal input signal is applied to the amplifier.
(b) Sketch the frequency spectrum of the output voltage
