Find an analytical expression for CTFT ofx(t)=e-2|t|. [Hint: Think of x(t) =g(t) + g(-t),where g(t)= e-2tu(t)]. Create a vector containingsamples of the signal y(t)=x(t-5) for a=0.01 and T=10 over therange t=[0: a :T-a]. since x(t) is effectively zero for|t|>5, you can calculate CTFT of gthe signal y(t)=x(t-5) fromthe above analysis using N=T/a.
Concentric spherical conducting shells in free space of radii r1 = 0.00113 m and r2 = 0.00220 m have a potential difference of 20.0 V (let the inner shell be at 0 V and the outer shell be at 20.0 V).
Sketch magnitude and phase responses (as linear gain versus digital frequencies) for each filter (use [0,π]). Indicate filter type. Find cutoff frequencies if sampling frequency in 30 kHz. Use 6 points only. Do not use MATLAB.
Write the 9S12DP256 assembly language instructions below a programmer could use to copy the 3rd variable from a 10-byte array into Accumulator B.
An opamp based integrator is measured at 1KHz to have a voltage gain of -100 V/V. At what frequency is its gain reduced to -1V/V. And, what is the integrator time constant
A transmitting antenna has a radiation resistance of 72 ohms, an effective resistance of 8 ohms, a directive gain of 20, and an input power of 100 watts. What is the antenna gain, radiated power, and EIRP
Determine the number of gates needed to implement a 4-bit carry-lookahead adder, assuming no fan-in constraints. Use AND, OR, and XOR gates with any number of inputs
Design a power supply using a 24V, center-tapped transformer to supply 12V at 500mA, -12V at 100mA and 5V at 250mA. What is the minimum current rating of the transformer
open a savings account to save retirement. Every month you put $100 into a savings account which pays 8% interest compounded monthly. At the end of each year you receive a $500 bonus which you place directly into your retirement fund
If someone presses the 1 or First floor button, the elevator should go to the 1st floor, open the door and remain in this state for a small amount of time, then close the door. Assume the elevator takes one clock cycle to travel.
you borrowed $10000 from a local bank with the agreement that you will pay back the loan in five years the pay back plan includes two parts: a graduated payment plan with the first payment set at 1500 at year 1 and a gradient of $600 afterward
At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h.
A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier.
