1. An 820-Ω resistor is connected in parallel with a 1000-pF capacitor. The impedance of the parallel combination is 410 - j410 Ω. Find the frequency.
2. Two impedances Z1 = 300 - j50 Ω and Z2 = 450 + j100 Ω are connected in parallel. Find the equivalent impedance of the pair.
3. A 100-mH inductor and a 100-Ω resistor are connected in parallel. The circuit is excited by a voltage source with vS(t) = 10 cos (1 kt - 45°) V. What is the steady-state current iS(t) flowing from the source?
A crucial step in showing that the waves in a fluid are necessarily longitudinal was the integral in (16.142). For an arbitrary function f (ξ), with derivative f'(ξ),
A separately excited DC generator rated at 125V has an armature resistance of 0.75 ohms and a no load coltage of 140 VDC. What will the armature voltage will be at rated load
Design a circuit that will check if a two digits decimal number is equal to a set ofpredefined number. If they are the same, then allow a door to be unlocked. Else, the doorwill stay locked. Can anyone give me some idea on this topic?
A 10 cm length of a K-band copper waveguide is filled with a dielectric material with er = 2.55 and tan f = 0.0015. If the operating frequency is 15 GHz, find the total loss through the guide and the phase delay from the input to the output of th..
An integral controller is used for speed control with a setpoint of 12 rpm within a range of 10 to 15 rpm. The controlleroutput is 22% initially. The constant KI = -0.15% controller output per second per percentage error.
Describe the operation of the series RC circuit. The discussion must address phase angle relationships of current and voltage. The answer must include the effect of source frequency on the voltage drops across the resistor and the capacitor at ver..
Using MATLAB, create a short script (m-file) to assign a value to the time variable, t, and then calculate the voltage, current, and power at that time.
Consider a zero-phase sine function, x(t), with frequency ?=1.3rad/sec. What is the minimum positive time shift needed to turn this function into a zero-phase cosine of the same frequency
Design of a toolbox to hold tools versus design of a wafer to hold the wires of a microscopic silicon chip.
Compute and plot the correlation sequences r s1s2 (l), r s0s0 (l), r s1s0 (l) and r s2s0 (l) . Compute and plot the cross-correlation sequences and of the received signal with the template signals and s 2 (n).
Search the web for status of and report on an installation of "Super Conductor" Cable, 2-3 pages.
Draw the waveform that results on output RB7. If the waveform is repeating, then say so and draw at least two cycles. Also, clearly indicate logic '0' and logic `1' on your waveforms.
