Can someone please kindlyanswer this (INCLUDING PART (B.)) with worked out explanations? Theproblem is that everyone is using nodal analysis and I am doingthis question using gain manipulation using input voltages andunderstanding input theory of op-amps.
Q4. The amplifiers employed in Figure 4a and 4b are ideal op-amps. a) Given that the input signal to the circuit of Figure 4a is vi 0.5 +0.5sin(at)v, determine the output voltages: vi(t), v2(t) and v (t). sketch the corresponding waveforms to the scale against time. [10 marks] b) Derive an expression for the output voltage, v of the circuit in Figure 4b Based on your derivation, design an amplifier that has an ac gain of 5 and a dc level at 6V.
