1. What is an ideal op amp? Compare the properties of a 741C to those of an ideal op amp.
2. Draw an op amp with an input voltage step. What is slew rate, and why is it important?
3. Draw an inverting amplifier using an op amp with component values. Now, tell me where the virtual ground is. What are the properties of a virtual ground? What is the closed-loop voltage gain, input impedance, and bandwidth?
A 78 Ohm lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75 Ohms?
Two capacitors, one 6.6 µF the other 29 µF, are connected in parallel across a 12 V battery.
Find the frequency and period of sine waves having an angular velocity of 754 rad/s, 8.4 rad/s, 6000 rad/s and 1/16 rad/s.
Draw an equivalent circuit representing each of the following power system components, showing all the circuit parameters in each case: (i) Short transmission line (ii) Medium length transmission line (pi and T circuits) (iii) Synchronous generator
what is the maximum load current for which the Zener remains in breakdown operation? For half this load current, what is the lowest supply voltage for breakdown opera-tion?
Assume that the Baud rate is 4800, and the clock input to the universal serial communication interface (USCI) module has a frequency of fBRCLK = 32,768 Hz. We want to set up the USCI module in the UART mode
if a circuit contains 3 automatic switches and we want that, with a probability of 95%, during a given time interval they are all working, what probability of failure per time interval can we admit for a single switch
Design and Analysis: The simple high-pass and low-pass filters shown to the right have been analyzed in class. The transfer functions are H-HP(f) = j fRC / ( 1 + j fRC ) and H-LP(f) = 1 / ( 1 + j fRC ). In either case the -3dB frequencies are F-3D..
a 50 kHz squarewave is input to the 60 kHz low pass filter. The filter is effective at rejecting frequencies higher than 60 kHz. a. Does it make sense that the output of the filter is a 50 kHz sinewave
For the circuit shown in Fig. 1, find the node voltages- For the circuit in fig. 2. find i1 to i4 using mesh analysis:-
Calculate mass, energy, entropy, and exergy balances for the following devices
Redesign the resistive load inverter. - Using the results of part (a), what is the input voltage range when the transistor is biased in the saturation region?
