Describe the operation of the series RL circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drolps across the resistor and the inductor at very loave and very high frequency values.
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
The respective resistance measurements (from the first bar) are 11.1 kW, 12.1 kW, and 14.5 kW.Find the a) material resistivity and b) contact resistivity, then c) restate the material resistivity as a sheet resistivity.
A sinusoidal current is zero at t = -0.625 s and increasing at a rate of 8000pi A/s. The maximum amplitude of the current is 5 A. a. What is the frequency of i in radians per second b. What is the expression for i
Consider a network with a driving-impedance Z. (1) Find expression for P and Q. (2) Find p(t) in terms of P and Q. (3) Suppose that the network is a series RLC. Interpret the result in part (2).
The counter will use the falling edge of the clock (denoted by Clk) and have a separte reset pin (R) which will reset the counnter to 0000 when it is low (e.g. R=0). Please use D type flip-flops. write down the state diagram , and state table.
Discuss the differences between, advantages and disadvantages of the following types of grounding systems: ungrounded, solidly grounded and high resistance grounded systems.
The sinusodial modulating wave m(t) = (Am)cos(2*pi*fm*t) is applied to a phase modulator with sensitivity kp. The unmodulated carrier wave has frequency fc and amplitude Ac. Determine the spectrum of the resulting phase-modulated wave
a 9.1 v zener diode exhibits its nominal voltage at a test current of 28 mA . at this current the incremental resistance is specified as 5 ohms . find Vz0 of the zener model . find the zener voltage at a current of 10 mA and at 100 mA.
An input signal of 10V at 0o and a frequency of 1592 Hz is applied to a series RLC circuit with resistor R = 100 ohm, inductor L = 40 mH, and capacitor C = 0.5 F. The value of the total circuit complex impedance is
placing the compensator or zero such that it will cancel the open-loop pole at -1. For both compensators you design, show the corresponding closed-loop transfer functions and compare the transient responses (P.O. and Ts).
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
False positive and false negative rates can be adjusted, and they are often complementary: Lowering one raises the other. List two situations in which false negatives are significantly more serious than false positives.
