Evaluate the following convolutions using the graphical approach:h1[n]=2u[n+1]-2u[n]h2(t)=2u(t+1)-2u(n)
y1[n]={2u[n+1]-4u[n]}*h1[n]y2(t)={r(t-2)-2r(t-4)+r(t-6)}*h2(t)Evaluate the step response of h1[n] and h2(t)
r=ramp funtionu=step funtion
A link is transmitting 10 Mbps in a bandwidth of 10 MHz using 1 mW of power. (Box 1) What change will you do to double the data rate and why (Box 2) How can you use the link if the noise were larger than the signal
Design a 2-bit counter that, when v = 1, counts in the repeating sequence: 0, 3, 1, 2, and when v = 0, counts in the reverse direction. (a) Construct a state diagram and state table. (b) Implement the counter using D flip-flops.
Calculate the unit step response of the DT systems with the following impulse responses: a-) h[k]= u[k+6]- u[k-10] b-) h[k]= 3^k- u[-k]
Open Neutral Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Port B, which is connected to an LED
Consider a multimode silica fiber that has a core refractive index of n1 = 1.48 and cladding index n2 = 1.46. Find the critical angle, numerical aperture and the acceptance angle.
Write a program that reads a file containing only integer, but some of the integers have embedded commas, as in 145,020. The program should copy the information to a new file, removing any commas from the information.
Derive the expression for TRANSFER FUNCTION and write the expression for magnitude and phase of H(f).
A 150-MVA 15/200-kV single-phase power transformer has a 0.018ohm resistance and a 0.075ohm reactance. The magnetizing impedance is j80 per unit. a.) Find the equivalent circuit referred to the low-voltage side of this transformer.
Describe the basic operation of the n-channel MOSFET, the relationship to VGS, VDS an IDS. This would include such things as accumulation, inversion, pinch-off point, etc. Which end is the drain
Consider a uniform electric field of 50 N/C directed toward the east. If the voltage measured relative to ground at a given point is 80 V, what is the voltage at a point 1.0 m directly west of that point
