Compute the Transfer EquationThe questions are for the equation: y"(t) + 6y'(t) + 34y(t) = 2x'(t) + 11x(t)
a) Compute the transfer equation Y(s)/X(s).
b) Compute the response of the system to the input x(t)=e^(-2t) u(t) assuming no initial stored energy.
c) Compute the response of the system to the input x(t)=4t^2 * e^(-6t) u(t).
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
Output levels of higher order products of a linear amplifier, If a tone is put into an amplifier, and its amplitude is increased by 1 dB, how much will the amplitude of the third-order products increase in dB?
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
Analysis of discrete time waveforms in z domain, A discrete time domain signal x(n) - u(n) - u(n-10) is decomposed and plotted. It is then examined in the z domian by appropriate transformation and algebraic manipulation.
In comparing the behaviour of an n-channel MOSFET with a p-channel device having identical geometry and threshold voltage, it is found that the n-channel FET has a greater drain current than that of the p-channel FET.
Write down the principle of energy conversion and give an example for single and double excited system.
The gain of the antennas must be increased when the TDMA system described in part (d) is used because the bit rate is higher than with FDMA and the noise power in the receiver is therefore higher
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
Implementation of the project with the analog and digital modulation techniques
Transfer function : key informaiton, A linear time-invariant discrete-time system is excited by the input x[n] = d[n] + 2u[n-1] (d represents δ(delta)). The resulting output response with zero initial conditions is y[n] = ((0.5)^n * u[n]). De..
Resisitive load, A 4:1 step down transformer uses a 60Vac source on the primary windings.
What is the RF bandwidth occupied by signal? What is the frequency range of the transmitted RF signal?
