Finding values of a composite discrete time signalA discrete time signal x(n) = x(n-1) + x(n-3) with initial conditions x(0) = 0, x(1) = 1 and x(2) = 2 is examined and the first 51 values n = 0 to 50 tabulated
Compute the unit-pulse response h[n] for the discrete-time system y[n+2]2y[n+1]+y[n]=x[n] (for n = 0, 1, 2, 3).
You have to figure out which one using cross or auto correlation.
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.
How many voice channels are carried by a E1 transmission given 8 kHz sampling and 8 bit words? Why is an end of frame marker always required in a digital telephony system?
Wavelength and Frequency, The downstream information (from the network to the customer) is transmitted at a wavelength of 1550 nanometers and the upstream information
The schematic of the traffic light controller
The network is used for voice communications. Is it possible for one mobile unit to connect to another mobile unit directly? What advantage is there in connecting through the hub?
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
Identify the bus types and the unknown variables of the power flow problem. Write the complete set of equations needed to solve the load flow problem.
Determine the phase relation between V o and i g for the given network if V g = 45sin(317t) and determine v o for the given network
What is the quantization signal to noise ratio SNRQ at the receiver output? e. If the SNRQ were to be raised to 96 dB, how many bits would the ADC and DAC need? What would be the bit rate on the serial link?
Determine the minimum signal to noise ratio (s/n) in dB required in each communication channel to achieve a data rate of 270 kbps?
