- Explain Voltage Follower circuit using Op-Amp.
Section B – sample questions
- Define Clamper. Determine output voltage for the given network. (Circuit: Vi=10V/-20V sinusoidal, 100µF capacitor, 10V battery, RL=10kΩ)
- An Audio frequency signal 10Sin(6π×400t) is used to amplitude modulate a carrier of 25sin(4π×10⁵t). Calculate: (i) Modulation Index (ii) Amplitude of each side band (iii) Total power delivered to the load of 2KΩ (iv) Bandwidth (v) Transmission efficiency
- Simplify the function F(A,B,C,D) = Σm(0,2,5,6,7,13,14,15) + d(8,10) using K-map and implement the simplified function using NAND gates only.
