Using 2 wattmeters as a method of power measurement,wattmeter #1 reads 400W and wattmeter #2 reads 300W. The load isknown to be inductive and fed from a 208/120V grounded-wye 3-phase4-wire system. Determine the power factor of the load and the linecurrent.
Using 4 PSK or 2 PSK with the same total power as a reference, calculate the Eb/No versus Pe waterfall plot and compare the asymptotic coding gain of the coder/encoder.
Calculate the numerical value of the mutual capacitance of a square parallel plate capacitor whose dimensions are 1 mm X 1 mm if the two plates are separated by a distance of 2 mm. The relative dielectric constant of the material between the two p..
a. Tablulate the truth table for an 8x4 ROM that implements these Boolean functions. b. Tabulate the PLA programming table for these functions. Minimuze the number of product terms. c. Implement this circuit using a PAL with 3 inputs, 4 outputs and 3..
1. Calculate the total (composite) load power factor, true power, reactive power and apparent power. 2. Also calculate the full-load current and the amount of capacitive KVAR needed to bring the overall power factor to .95 lagging.
Sketch a Bode plot for the frequency response of a High-pass R-C filter where R=470ohms and C=0.047uF. Draw the circuit, calculate the actual cutoff frequency, and calculate the dB level at one-half the critical frequency and twice the critical fr..
Find the appropriate subchannel modulation format (note: the number of constellation points in the modulation mapping scheme should be the power of two).
If a 250 us period clock signal must be transmitted with a 10 kHz data signal on the same link, then what is the minimum bandwidth necessary to support both signals.
Vary as square root-application, The frequency f of vibration of a wire varies directly as the square root of the tension T of the wire
consider a 3λ/4 linear wire antenna which is fed at the center,find : i- the current distribution on the wire. ii- for the input current of .7 Amp, find the loop current (I0) , and the maximum radiated E at r = 1000 m
Construct a ladder schematic of a series cirucit with a DC source, overload protection, ground, and a SPST control operating a lamp.
Calculate the armature current, total losses in the machine, and the I^2R losses in the armature. Help would be greatly appreciated as my calculations for Armature Current Ia is in my mind way too high, 480A. Then calculate the losses in the armat..
Two amplifiers are cascaded, one with a voltage gain of 6 db and the other with a voltage gain of 4. if 1 V is applied at the input of the first amplifier, what is the voltage at the output of the second amplifier
