Fig. 2.2 *For the Op Amp in Fig. 2.2. Evaluate the Av. (5) *Recommend a generalized Op Amp amplifier which processes sin wave into a cosine wave (1-5), a square wave into a triangular wave (1.5), a constant DC signal into a zero-output signal (1.5) and a square wave into an impulse signal (1.5). *Recommend an Op Amp averaging amplifier such that vin (avg) = -Vo. Use for inputs from vini to vins in ascending order. Choose input resistances as 100k12 and feedback resistance as 25k 2. (4)
