A switch, a 220 resistor, and a 60 mH inductor are in series across a 20 V battery.
What is the current through the inductor two time constants after the switch is closed?
Using bit-slicing technique, design a circuit that calculates the expression 2*a-b. Operands a, and b are each 4 bits long. The result is represented using 5 bits. Show the transistor-level design using dynamic circuits.
Draw a block diagram for a datapath that contains: an 8-word, three-port register file; an ALU that accepts operands either from the datapath or from an external source; and a shifter that shifts the A operand from the register file before it goes..
An electric motor is monitored with an ammeter, voltmeter, and wattmeter, which indicate 5.2A, 120V, and 480W respectively. Assume 60Hz. A) Draw the phasor diagram of the voltage and current,assuming the voltage at zero phase and lagging current.
A lossy transmission line at 1GHz has the following characteristics: Z0= 50.0 ohms alpha= 0.01 dB/m, Betta=8 rad/m. Determine R, L, G and C for the line
Is there any advantage of star connection over delta w.r.t. induction motors? Also, is there any advantage or disadvantage of star connection over delta w.r.t. distribution and transmission of power? Please explain the reasons for all the advantag..
Indicate the closest value to the change in decibels of the received signal for the given parameter change. The distance between transmitter and receiver for a one-way communication path is halved.
Using nodal analysis find the output voltage VO in fig.1- Use nodal analysis to find VA and VB in the network in fig 2.
Write down the principle of energy conversion and give an example for single and double excited system.
