a. Describe what you understand by 'offset voltage' and 'offset current' of op-amp. Discuss with a neat circuit diagram the method used for minimizing offset voltage and offset current in an inverting amplifier. (10)
b. Measure the output voltage 'V0' for the following non-inverting op-amp summer with V1 =2V and V2 = -1V
Q. Explain Demodulation of DSB? Demodulation of DSB SC AM signals requires a synchronous demodulator, which is also known as coherent or synchronous detector. That is, the demo
in DC series generator we consider Eg=V+Ia(Ra+Rse).But in DC shunt generator why it is only Eg=V+IaRa and not Eg=V+Ia(Ra*Rsh/Ra+Rsh)
The goal of this project is to model a system and to design a controller for the system so that the closed-loop system performs satisfactorily.
Q. Show Binary Coded Decimal Number System? If we analysis single digit values for hex, the numbers 0 - F, they represent the values 0 - 15 in decimal, and occupy a nibble. Fre
Q. A three-phase load, connected to a 440-V bus, draws 120 kWat a power factor of 0.85 lagging. In parallel with this load is a three-phase capacitor bank that is rated 50 kVAR . D
1. Find the general solution y(t) of the ordinary di erential equation where ω is a non-negative constant. (Consider the ω = 0 and ω > 0 cases separately). 2. Use Laplac
Q. What is the principle of operation of an integrating circuit? The RC integrator is typically a series RC circuit that uses the capacitor to develop its output. Since voltage
