A message signal, x(t) has a bandwidth of 15 kHz and an average power of 0.5 W. This signal is to be uniformly quantized with an input range of range of +-5 V. What is the bit rate of the corresponding PCM signal if the SQNR is to be greater than 30 dB?
a) If the internal resistance of a voltmeter is 100x bigger than the output impedance of a circuit, what is the loading error b) If the internal resistance of an ammeter is 10x smaller than the output impedance of a circuit
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
What are the essential features of an ideal op amp? Identify the terminals of an op amp. Draw its equivalent circuit. Define virtual ground and what is difference amplifier? Draw its circuit. Define C.M.R.R.
The fuel tank contains 33 kWh per gallon. If the vehicle were to be replaced by an electric vehicle that charges from the power grid, how much power would it draw (in W, kW, or MW) to recharge at the same rate as the gasoline powered automobile
A system has the following input/output relation: y(n) = x(n) + .5 y(n -1). If the input x(n) is the sinusoidal signal shown in problem 1.32(d) (Above), the steady-state output will have the following form: y(n) = A sin(Bn+C). Determine the value ..
two loads connected in parallel are supplied from a single phase 240v rms source. the two loads draw a total real power of 400 kw at a power factor of 0.8 lagging. one of the loads draws 120 kw at a power factor of 0.96 leading.
modify the Very Simple CPU to incorporate a new 8-bit register,R, and two new instructions. MVAC performs the transfer Râ†AC and has the instruction code 1110 XXXX; MOVR performs the operation ACâ†R and has the instruction code 1111 XXXX.
Contains basic function in MATLAB files. Write MATLAB script(s) to plot the basic signals below in two subplots. The upper subplot should be a continuous waveform (don't do g) and the lower subplot should be a discrete plot.
Discuss the operation of a JFET, including the pinch off and gate-source cutoff voltage in your explanation. Discuss how you can tell whether an FET is operating in the ohmic region or the active region.
A set of digital scales is required to measure a load of 1000 N with an accuracy of ±1 N. Determine the minimum output resolution of the required ADC.
Determine the minimum bandwidth, baud, and bandwidth efficiency for the following bit rates and modulation schemes - 8-QAM and 16-QAM. Fb = 2400 bps Fb = 4800 bps Fb = 9600 bps
Suppose you have a line charge and a point charge in space. A point charge of 16nC is located at Q(2,3,5) in free space, and a unifor line charge of 5nC/m is at the intersection of the planes x=2 and y=4. If the potential at the origin is 100V, fi..
