1. A voltage v (t) = 100 cos 3 k (t) V is applied across a series connection of a 33-kΩ resistor and 3300-pF capacitor. Find the steady-state current i(t) through the series connection.
2. A complex load is driven by a current source i (t) = 50 cos 5 k (t) mA. The voltage measured across the load is v (t) = 100 cos (5 kt - 85)V. Find the impedance of the load and determine what two elements R, L, and/or C are equivalent to it.
Determine (a) the input to the detector, (b) the optimum threshold (to be compared with the detector input) that minimizes the average probability of error, and (c) the average probability of error.
A spherically-symmetric charge distribution in free space (with a
A 3000-V, 1-A dc power supply is to be designed with less than a 4 percent ripple voltage. Compare the pros and cons of implementing this power supply with half-wave, full-wave, and full-wave bridge rectifiers.
For the simple equivalent circuit of 0.017 m2 PV cell shown below, the reverse saturatoin current is I0= 4 * 10-11 A and at an insolation of 1-sun the short circuit current is Isc = 6.4 A. At 25 degrees C
Explain using concrete examples the enormous appetite of multimedia applications for transmission capacity. What importance could ADSL have as a medium-term solution.
A string of Christmas tree lights of eight (6W, 15V) bulbs connected in series. a) What current flows when the string is plugged into a 120V outlet b) What is the resistance of each bulb
Given a function G = K/(s + 5)^2 and needing to design a lag network that needs a phase margin of 45 degrees and a steady state error of 5% how do you calculate aplha and tau for the compensator function Gc(s) = (1 + tau*s)/(1 + aplha*tau*s)
the transformer is to be connected as an auto transformer to supply a load at 120 V from a 210 V source. What kVA load can be supplied without exceeding the current rating of the windings (assume an ideal transformer for this part)
Binary data is transmitted at the rate of Rb bits/sec over a channel occupying a bandwidth B and the channel SNR=3 dB. If the data bit rate is increased to 2.65Rb and the bandwidth is increased to 1.75B i.
