Fourier Transform & Properties
x(t)is given in the below illustrated figure.
Find and plot the frequency response of x(t)
Find and plot the frequency response of x(2t)
Find and plot the frequency response of x(-2t-6)
For the second object, at a location corresponding to the point of measurement on the first object, determine the vapor concentration and partial pressure. If the average heat flux q" is 2000 W/m2 for the first object determine the average mass fl..
Two loads connected in parallel are supplied from a single-phase 240-V rms source. The two loads draw a total real power of 400kw at a power factor 0f 0.8 lagging. One of the loads draws 120kW at a power factor of 0.96 leading. Find the complex po..
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
a binary transmission channel introduces bit errors with probability 0.15.estimate the probability that there are 20
Determine the approximate output rating (kVA) required for a portable alternator to be used as temporary supply on a single dwelling construction site. The loads to be supplied include: 1 x 1 kW single-phase capacitor start/capacitor run motor (bri..
Use Gauss's law to obtainexpressions for the electric field intensity E in both regions: r> a and r
For each of the discrete signals below, determine mathematically whether the signal is even, odd, or neither. (a) x[n]=6u[n-3] (b) x[n]=-n (c) x[n]=sin(n-(pi/6))
A circle, centered at the origin with a radius of 2 units, lies in the xy plane. Determine the unit vector in rectangular components that lies int he xy plane, is tangent to thte circle at 3.
a signal franging from 1khz to 100khz will be put into a davice that will need amplification that will output to speakers. A 12v battery is available as a power source, however the current out of the battery should be kept to a minimum.
The system phase margin frequency is given as ω1 =1.7 radsec-1 and the required phase angle is 50°. Obtain the respective values of the PID controller.
a square wave of 1000Hz is introduced into an ideal band passfilter (bandwidth = 100Hz) that is tuned to 5000Hz. Thesignal output has an amplitude of 0.1V. The filster is thenreturned to 9000Hz. Sketch the output waveform and calculate itsnew ampl..
Assume initially that no inputs have been seen and create a special initial state with output 0 to start the Moore machine. Draw a state graph for a Moore machine (minimum number of states is 5).
