building an audio amplifier

building a audio anplifier

Design an audio amplifier system ( with components of your choice from problem1) with the following specifications:
(a) Mid frequency voltage gain of at least 100, variable
(b) Low frequency cutoff F1 of 50 Hz ( with a roll off 40 db/decade to lower frequencies
(c) High frequency cutoff F2 of 5Khz ( with a roll off 40db/decade to higher frequencies
(d) Input impedance Rin = 2k; Output impedance Rout = 2K
(e) Study the response at Load RL varying from 20K to 2K in steps of 2K

Components from problem 1
Diodes ( Normal, Schotky, Zener and Varactor Diodes)
Bipolar Transistors (NPN & PNP)
OP.Amps
FETs ( JFETs N-gate and P-gate; MOSFETs: N Channel and P Channel)

use opamps in high pass, low pass and bandpass configs for the frequency selectivity, for input and output resistance use L matching networks, and for gain can be done with the op amps. anything else i'm missing? this reminds me of basic color mixer circuits we had to design in intro to electronics class, i reccomend doing your own homework if thats the case otherwise your degree will be fairly useless.
