The forward transmittances of unity feedback tracking systemsare given below. For each, find the type number of the system, thesteady state error coefficients k0,k1, and k2 and the steady stateerrors to unit step ramp, and parabolic inputs.GE (s) = 2/(s3 + 2s2 +7s)
A new 24-bit processor is being designed for operation in a cell phone (you can assume the word-size is 24 bits). Suppose the following memory values are being stored in memory that is organized where each location is 8-bits wide (byte addressable..
An OFDM system employs 260 data subcarriers, 40 pilot subcarriers, and 34 guard subcarriers to transmit data through a wireless channel. QPSK modulation is employed for each subcarrier.
Consider the LTI described by the following input-output relation: y[n] = 3/4y[n-1]-1/8y[n-2]+x[n] a)Find system function H(z) and check is system is stable. b)Determine impluse response h[n] of system
Develop a control system to fill a container with water after it is emptied through a stopcock at the bottom. The system must automatically shut off the water when the container is filled.
In rectangular form (numerical values required to nearest 0.1) what is the input impedance of a λ/8 section of 50 ohm line connected to a 200 ohm load. Include a figure showing the configuration having the input impedance to be calculated.
Vgs is the switchcontrol voltage. Find the switch on-resistance Rds and the voltageVds obtained when Vgs=5V and Id=1mA. If μp=0.5μn what must bethe PMOS device W/L to provide the same NMOS on-resistance. AssumeVtn=|Vtp|.
Compute y(nT) iteratively for n=0, 1, 2, when, y(-T)=2, and x(nT) = u(n) Hint: the initial conditions are given for negative n. Shift the equation to the right to express x() and y() to eliminate all advances and end up with x(n), y(n)
Transmission line A coaxial transmission line has characteristic impedance Z0 = 50 ohms and has length L = 200 m and phase velocity vp = 2.0e8 m/s. The end at x = 0 is terminated with Rs = 50 ohms and the end at x = L is terminated with RL = 75 oh..
