Toss a fair coin until the first head is obtained. Let X be the number of tosses until the first head is obtained. Compute and draw the pmf and cdf of X.
a positive test charge is used to explore the field of asingle positive point charge Q at P(a,b,c). if the test charge isplaced at the origin, the force on it is in the direction0.5ax-0.5sqr(3ay), and when the test charge is moved to (1,0,0)
Design a first-order digital highpass chebyshev filter (.5-db ripple) with a cutoff frequency of 850 Hz and a sampling frequency of 10 kHz. Determine the transfer function using BLT.
A proportional controller for a rotating antenna has a gain Kp of 5 in-oz/deg. The antenna was initially pointing due south, but was then commanded to point southeast. What is the torque when the antenna gets to within 5o
The Ic was measured for different values of a load resistance. It was noticed that Ic was pretty much constant for the first 1900 ohms values, but then it suddenly decreased. Why did that happen
The signal x(t) consists of sum of two components, x1(t) and x2(t). The signal x(t) is bandlimited to 40 kHz, and it is sampled at a rate of 100 Khz to yield the sequence x(n). It is desired to suppress the signal x2(t) by passing the sequence x(n) t..
Draw an equivalent circuit representing each of the following power system components, showing all the circuit parameters in each case: (i) Short transmission line (ii) Medium length transmission line (pi and T circuits) (iii) Synchronous generator
64-bit ripple-carry adder and a 64-bit carrylookahead adder with 4-bit blocks. Use only two-input gates. Each two-input gate is 15μm2, has a 50 ps delay, and has 20 pF of total gate capacitance. You may assume that the static power is negligible.
Design a circuit that lets exactly one full negative pulse (from an input train of pulses) pass through to the output, after a button is pushed.
Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the pack..
A 2000 KVA, 4800-600V, 60 Hz, core type transformer operating at no load in the step down mode draws a magnetizing current equal to 2 percent rated current. The core has a mean length of 3.15 m, and is operating at a flux density of 1.55 T.
A factory is to be supplied with 408Y/277 3 phase, 4 wire electrical service. The total estimated single-phase load is 25 kW, at .9 lagging power factor. The total estimated three-phase load is 250 kW at .85 lagging power factor.
Consider an industrial load that absorbs 40 kW of power with power factor 0.8 lagging from a 60-Hz transmission line of voltage VL= 240
