calculate the convolution (x1[x]*x2[k]) for the following pairs of sequences:
a-) x1[k]=u[k+3]-u[k-2] and x2[k]=u[k+5]-u[k-4]
b-) x1[k]=0.5^k u[k] and x2[k]=cos Pi*k u[-k]
Describe the charge diffusion and drift in a PN junction, without and then with an applied voltage
A certain battery has terminals labeled a and b. The battery voltage is vab = 12 V. a) To increase the chemical energy stored in the battery by 600J, how much charge must move through the battery
A circular line charge of uniform line charge density q(C/m) is located in z=0 plane with its center at the origin. Determine, a. The electrostatic potential V at a point along the z-axis (0, 0, z) b. The electrostatic field E a point along the z-axi..
Dispense requested amount using least number of bills, Write a C program for an automatic teller machine that dispenses money. The user should enter the amount desired (a multiple of 10 dollars)
In class we saw an example of 'Beat note'. In this problem we consider a more general case. Let fc > 0, fd > 0 and define a signal x as.
Analyse and Model Engineering Situations and Solve Engineering Problems using Laplace Transform
A truncated cone has a height of 50cm. The circular faces on the top and bottom have radii of 20 mm and 1mm, respectively. If the material from which the solid cone is constructed has a conductivity sigma of 2 x 10^6 S/m.
Earth-based 802.11a or 802.11g wireless LAN standards transmit data using a bandwidth of 16.56 MHz. What is the theoretical thermal noise level (in V) in an ideal receiver operating with an input impedance of 50 ohms
The ATSC broadcast television system used in the US transmits video signals at an average rate of 18.34 Mbps and employs 8-VSB modulation.
Let x[k] be a time-domain sequence and X[r] be its DFT. (When written as vectors, unless stated otherwise, always assume the first entry in the vector is at k=0 or r=0, respectively.) If x[k] = [5, 9, 6, 10]
