Using Multisim, create the following waveforms and state if each waveformiscausal ornon-causal,periodic ornon-periodic:
(a) A step voltage switching from 0 to 5 V at t = 100 ms.
(b) A triangular wave that has amplitude of 75 V and a period of 10 ms.
(c) A cosine with amplitude of 100 V, radian frequency of 2000π rad=s, and a phase shift of -45°.
(d) A positive sawtooth wave with amplitude of 5V and a period of 100 ms.
(e) A charging exponential starting at -10 V and growing to + 5 V with a TC of 1 s.
An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt). a) Find the power of the modulated signal. b) Find the frequency deviation Δf. c) Find the phase deviation Δφ.
a)How many coulombs of charge are stored in the battery when fully charged?
The electric motor in a street car develops a power output of80 hp at 1200 rpm as the vehicle moves up a hill at a speed of 30mph. Assume the gearing losses are negligible, calculate: (a) The torque developed by the motor.
A pipe of inner radius 4 cm, outer radius 6 cm, and infinate length is centered on the z-axis. Charge is evenly distributed within the wall of the pipe in the amount of 16 coulombs per meter length.Find and Plot the electric feild density as a fun..
How much time will it take to rotate the part 180°?
A certain element has a phasor voltage of V=86.6+j50 V and the current I= -2.5+j4.33 A. The angular frquency is 200rad/s. determine the value of C to two significant figures with appropriate units.
1.xyz corporation is a manufacturer of widgets. over the past several months it has been selling its widgets for 100
A 200 hp, 230 V, 500 rpm separately excited dc motor is controlled by a chopper. The chopper is connected to a bridge-diode rectifier supplied from a 230 V, 3 phase, 60 Hz ac main. The motor chopper details are as follows:
Given the voltage divider supply of given figure: - Determine the supply voltage E, - Find the load resistors RL2 and RL3.
Show how to make a two-digit digital-to-analog converter by appropriately scaling the input resistors of a summing amplifier. The digital input represents two digits, each consisting of four lines that represent the values 1, 2, 4, and 8 for the r..
