Q. Internal Frequency Compensation of operational amplifier?
Some op amps, such as the 741, have internal RC networks which are intentionally designed to reduce gain at high frequency. The result is that the open-loop gain begins to fall at a few hertz and then has a characteristic falling at 20 dB/decade or 6 dB/octave (i.e., gain ∝ 1/f ) until eventually the gain becomes unity (0 dB) at about 1 MHz.
Q. Explain Thevenin and norton equivalent circuits? For a linear portion of a circuit consisting of ideal sources and linear resistors, the volt-ampere (v-i) relationship at an

Q. For themagnetic circuit shown in Figure, neglecting leakage and fringing, determine the mmf of the exciting coil required to produce a flux density of 1.6 T in the air gap. Them
Q. Explain about Transistor Amplifiers? Amplifiers are circuits that produce an output signal which is larger than, but proportional to, an input signal. The input and output s
Traditional Model - Performance Monitoring and Control The traditional model talks only about the finance and the financial accounting model. The output are published periodic
Q. Determine v, i, and the power delivered to elements in the network given in Figure. Check whether conservation of power is satisfied by the circuit.
Define the term real time clock. A real-time clock maintains the time in real time, which is, in hours and minutes. For the real-time clock the software contains an interrupt
