A DT system has the unit pulse response h[nT] = (0.4)^-|n|. Find and plot the system zero-state response to the input signal
x[nT] = u[(n+2)T] + u[(u-2)T]
A 1900x10^(-6)F capacitor, intially cahrged to 120V, is discharged by a steady state of 120x10^(-6)A how long does it take to discharge the capacitor to 0V
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.
In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What mass of copper is deposited in 10.0 minutes. Avogadro's number is 6.022 × 1023 molecules/mol and e = 1.60 × 10-19 C.
PLL can be used to demodulate an FM signal. If you are tuned to an FM station at a frequency of 101.1 MHz, the free-running frequency of the VCO must be set to what frequency
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
An FM signal being transmitted is represented by eFM(t) = 50Sin((2)(95.1)(106)t+2Sin((2)(10)(103)t)). If the antenna impedance is 75 , determine: (a) total power in FM signal and (b) FM modulation index.
If the segment base 002Bh with offset 0013h maps to physical address 002C3h in memory, what will be the segment base that will map to same physical address 002C3h using an offset of 0003h
The input capture option on the HCS12 is used to measure the period of a 100 Hz signal. With an E-clock of 24 MHz and no scaling, how many overflows will occur Assume the free-running timer starts at 0x0000.
Analysing spectrum anlyser output, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the follow..
The following signals are sampled using a train of impulses with periodicity kT: signal x(t) Is sampled to obtain and signal y(t) Is sampled to obtain yc(t) Determine the range of values for T that allows complete recovery of x(t) from xc(t)
(b) Verify that there are 4.994×(10 to the power 22) atoms per cubic centimeter in the Si lattice at room temperature. (c) Determine the center to center distance between nearest neighbours in the Si lattice.
