the voltage v in a certain circuit is described by the differential equation 3v"+24v'+75V=0a) determine the values of α and w0b) what type of damping is exhibited by V(t)?c) determine v(t) for t0, given that V(0)=10V and v'(0)= 50v/s.
Assuming that only integer multiples of a unit bipolar transistor having IS = 3 x 10-16A can be placed in parallel, and only a single voltage source, VB, is available (Fig. 4.54), construct the required circuit with minimum number of unit transist..
Writea program to simulate a lottery drawing that uses balls numbered from 1 through 10. Assume that three balls are drawn at random (Userandom numbers or allow user to input the number of lotterydrawings to simulate the random ..
A customer has a 2 story house and needs a whole house fan to run on timers, 1 on each floor, the ability to choose high or low speed on either floor, and signal lights to show if in high or low speed on each floor. The diagram has 4 single pull s..
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
Design a digital circuit that can be attached to a school bill which can work automatically from 7:00 AM to 12:45 PM, and it has the following features: 1- Rings for 5 seconds. 2- Start ringing 7:00 AM to announce for the field gathering. 3- Rings 7:..
Suppose 33 mL of 1.20 MHCl is added to 42 mL of a solution containing excess sodium hydroxide, NaOH, in a coffee-cup calorimeter. The solution temperature, originally 25.0C, rises to 31.8C.
Given: A 13.8 kV circuit has a load of 6000 kVA with a lagging power factor of 0.8. Required: How much capacitive reactive power is needed to correct the power factor to 0.92 lagging
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
A uniform plane E field, polarized in the x direction travels in the negative y direction in dry earth (Er = 16, Mu(r) = 1) with a phase constant Beta = pi rad/m and an amplitude of 4.0 A/m. If this field has its maximum value at t = 0, y = 2
Consider an analog periodic sinusoid x(t)=cos (3*pi*t +pi/4) being sampled using a sampling period Ts to obtain a discrete time signal x(n)=x(t)|t=nTs = cos(3*oi*Ts*n+pi/4). Choose a value of Ts for which the discrete time signal is x(n)
The power measured by a Prony brake attached to an engine flywheel is 3.8 brake horsepower. The indicated horsepower, as measured by means of indicator cards is 4.1. What is the efficiency of the engine
