In a satellite radio system, 128 stations of stereo quality are to be packaged in one data stream. For each station, two(left and right) signals of bandwidth 15,000 hz are sampled, quantized, and binary coded into PCM signals. The transmitter must multiplex the data from the 128 stations into a single stream via time multiplexing.
A: If the maximum acceptable quantization error in sample amplitudes is 0.25% of the peak signal voltage, find the minimum number of bits needed for a uniform quantizer.
B: If the sampling rate must be 20% higher than the Nyquist rate, find the minimum bit rate of the multiplexed data stream based on the quantizer of part(A).
C: If 5% more bits are added to the multiplexed data for error protection and synchronization, determine the minimum bandwidth needed to transmit the final data stream to receivers.
In a processing plant, jars on a conveyer belt are cleaned out with a high-pressure air jet just prior to being filled (Figure Below). When a jar approaches the cleaning station, it activates a switch (with both NO and NC contacts).
Consider the transformer to deliver its rated kilovoltamperes at 0.80 power factor lagging to a load on the low-voltage side with 240 V across the load. Find the highside terminal voltage.
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
A 10-bit unipolar ADC with a reference of 5.00 F and a 44 micro seconds conversion time will be used to collect data on time constant measurement. Thus, the input will be of the form V (t) = 4(1-e^t/T) . What is the minimum value of T
Four voice signals. each limited to 4 kHz and sampled at Nyquist rate are converted into binary PCM signal using 256 quantization levels. what will be The bit transmission rate for the time-division multiplexed signal.
steam flows through a turbine one inlet and two exits with know condition at the steady state ( hints: h1=3231KJ/kg, h2=2812 KJ/kg , specific volume (v)= 0.0994 m^3/kg , at p= 30 bars,v=0.4045m^3/kg, at p=5 bars, no potential and kinetic energy ch..
A 4800/480 volt, single phase transformer is rated at 75KVA. test results performed for rated power showed the following. short circuit test V=80v, P= 2470W, I= Rated current open circuit test V= 480v, I=4Amp, P=616W
Suppose that the source charges of the two previous problems are present together. The potential at infinity is defined to be 0. a. Is the potential at the point (0.5, 0.5, 0.5) positive, negative, or zero b. Is the potential at (4, 4, 4) positive
Discuss the sequential nature of the Ripple Carry Output Adder. Why is it actually a sequential operation What are problems associated with this type of sequential design? How would you alleviate them
An amplifier with an input impedance of 50 K-ohm, an open circuit voltage gain of 150 V/V, and an output impedance of 100 ? is connected between a 5 K-ohm signal source and a 1 K-ohm load.
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
Assume that this whole system is linear, so that, if the pressure on a sprinkler is halved, the area covered (as well as the flow rate) will be halved. This is true until the pressure is reduced below 20psi, at which it does not work at all.
