A baseband signal has frequencies from near dc to 4 kHz. To ensure ease of recovery, the signal is to be sampled at a rate 25 percent greater than the theoretical minimum. Determine the time interval (in ms) between successive samples.
The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage. Calculate the power angle if the network receives an inductive reactive power of 50 MVA.
A CB amplifier is operating with RL = 10kΩ, Rc = 10kΩ, and Rsig =100Ω. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source. What is the resulting overall voltage gain. Assume α ≈ 1
Two full charged 8A-Hr batteries are connected in parallel and supply power to a resistive load of 2.4 ohms. The open-circuit voltage of both batteries is 6.4VDC and the internal(Thevenin) resistances are 0.24 ohms and 0.28ohms.
how to design boost converter and inverter parameters?
The receiver uses a 10.7 MHz IF. For cost, power, weight and size reasons, it is desirable to use a single clock oscillator that will provide the frequency reference for the synthesizer, as well as providing the clock for data.
A R-C high-pass filter contains a 1 µF capacitor and a 1k resistor. Suppose a single "square" voltage pulse of 5 V for 1 ms duration is applied to the input. Carefully and neatly sketch the resulting output, including numeric values, of output volt..
A man has set up a Christmas display using 20 strands of lights (500 Watts/strand). If the man wants to wire the strand outlets to the house panel with a 30 amp breaker, Determine a) The number of 30 amp parallel circuits Cratchit will have to wire..
A 2-kHz sound wave traveling in the x-direction in air was observed to have a differential pressure p(x,t) = 10 N/m^2 at x = 0 and t = 50 μs. If the reference phase of p(x,t) is 36 degrees, find a complete expression for p(x,t). The velocity of so..
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.
A person fishing from a pier observes that 6 wave crests pass by in 7.3 s and estimates the distance between two successive crests to be 3.8 m. The timing starts with the first wave crest and ends with the last.
Find the appropriate subchannel modulation format (note: the number of constellation points in the modulation mapping scheme should be the power of two).
An input signal of 10V at 0degrees and a frequency of 1592Hz is applied to a series RLC circuit with resistor R=100ohm, inductor L= 40mH, and a capacitor C=0.5uF. The value of the total circuit complex impedance is
