Study code acquisition in frequncy hopping spread spectrum communication systems.Describe and explain why it is necessary.Design and demonstrate a code acqusition method.
The available circuit components are NMOS transistor, PMOS transistor, resistors, capacitors and inductors. Ideal sources can only be used to generate the supply voltage VDD & GND.
Find the inverse z-transform, x(n), of the following functions by bringing them into a form such that you can look up the inverse z-transform from the tables. This will require some algebraic and /or trigonometric manipulation/calculation.
Consider the simple model for HTTP streaming. Suppose the server sends bits at a constant rate of 2 Mbps and playback begins when 8 million bits have been received. What is the initial buffering delay
Perform the calculation from t = 0 to 20 s with step size of 1 s. Use an initial condition that the parachutist has an upward velocity of 20 m/s at t = 0. At t = 10 s, assume that the chute is instantaneously deployed so that the drag coefficient ..
The O.C and S.C test data are given below for a single phase, 5 kVA, 200V/400V, 50Hz transformer. O.C test from LV side:200V 1.25A 150WS.C test from HV side:20VV 12.5A 175W
Consider an impedance Z = (1 + j) Ohms. The voltage phasor across it is 1 V. What is the apparent power consumed on this impedance. b-) What is the real power consumed on the previous load.
An analog signal, containing frequencies up to and including 400Hz, is to be sampled at the minimum possible frequency, with a frequency resolution of 0.1 Hz. You are to find the sampling frequency, record length, and number of samples.
Design limiter circuits using only diodes and 10-k ohm resistors to provide an output signal limited to the range: (a) -0.7V and above (b) -2.1V and above (c) ±1.4V Assume that each diode has a 0.7-V drop when conducting.
Design a synchronous counter with a count sequence of all prime numbers between 3 and 15. Give the excitation equations. Map any unused counter states into the state whose output is the largest prime number output by this counter q.
A shunt-connected a DC motor has zero rotational losses and RA = 0. Assume that RA and Radj is constant [except in part (d)] and that φ is directly proportion to field current. For VT= 200 V and Pout = 2 hp.
A pool of 200 frames exists for paging of processes A, B, C, D, and E. The processes' page sizes are 100, 200, 50, 150, and 500, respectively. Assuming proportional frame allocation is being deployed, how many frames are allocated to process D
write a program that calculates the quadratic equation. the program should be able to compute imaginary numbers (i.e. sqrt(-1)). finally, output the tow result. hint: the computer cannot directly compute imaginary numbers
