Design a linear unregulated power supply that will provide an average of 500mA to a load at 15 volts average. Use a 12.6 VRMS sinusoidal source.
1- for the linear system : Sak y(n-k) = S br x(n-r) , (series a are from k=0 to n ) & ( series b from r=0 to m) a- find H(z) b- does this equation uniquely specify the unit sample response of l.s.i system c- choose, stable and casual system ,discuss ..
Given that each individual resistor can dissipate up to 1 watt of power before burning up, how much total power in watts ( W ) can the smallest-valued composite resistor dissipate before burning up
The Russian president and the Chinese counterpart need to come to an agreement by telephone. Neither can speak and understand each other's language. They need to employ translators. Compare this layered communication to OSI layers.
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
Important information about RC Series Circuit, An RC series circuit has a voltage source of 10Vac, a resistor of 10ohms, and a capacitor with an impedance of -j10ohms
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication. The AWGN single-sided power spectral densit..
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
Let x1[n] = {-2,1,-3,-5,6,8} with arrow under -2 and x2[n]={1,2,3,4} with arrow under 1. a) determine circular convolution of 7 between x1[n] and x2[n] b) verify (a) calculations by computing the DFTs and IDFT.
What is the change in the potential energy of the charge Q=1nC that has been moved from the point with the potential 2V to the point with the potential of 5V
(1) If the frequency was changed, what would happen to the current in a circuit Explain increase or decrease. (2) If you have R = 2 K ohm, Xc = 3 K ohm, XI = 4 K ohm . Find the G, Bc, BI, Yt anf Zt.
A new phone company wants to provide very cheap voice-only cell phone capability to 200,000 simultaneous users in San Francisco. They transmit only 8kbs per duplex channel using FDMA (frequency division multiple access) and BPSK (1 bit/Hz).
For a symmetric dielectric slab waveguide with the following parameters: n2 (core)=1.7, n1 (cladding) = 1.6 Calculate the range of core thickness such that the waveguide supports TE0/TM0 and TE1/TM1 modes but not TE2 modes.
