Consider the problem of performing system identification as shown previously in Figure 9.49. Suppose the system to be identified is the following IIR filter.
Write a MATLAB program that uses the FDSP toolbox function f lmscorr to identify a model of order m = 50 for this system. Use an input consisting of N = 2000 samples of white noise uniformly distributed over [-1, 1], a relative step size of α = 1, and the default smoothing parameter β.
(a) Plot the learning curve.
(b) Plot the step sizes.
(c) Plot the magnitude response of H(z) and W(z) on the same graph using a legend where W(z) is the adaptive filter using the final values for the weights.
an object hose mass is 200 kg moves at a velocity of 50m/sec and altitude of 200m,both measuredc relative to the surface of the earth. the acceleration of gravity can be taken as constant at g=9.8 m/sq.sec.
Suggest how a new plate could be made to ensure transmission is achieved at only one of these wavelengths.
The film is developed with an overall gamma of 2, reinserted in the position of the film during recording and reconstructed using the same point source as that used to construct the hologram. Using laws of ray tracing of the hologram, find and cha..
The band-limited continuous signal x(t) is sampled with impulse train p(t) with sampling period of T seconds. The output of the sampling circuitry is converted to sequence and is passed through a discrete time system with input of yin[n]
Using 3kohm resistors and ideal op amps, design a low-passunity-gain butterworth filter that has a cutoff frequency of 20 khz and is down at least 25 dB at 100 khz.
A 66-kV single-core lead sheathed cable is graded by using two dielectrics of relative permittivity 5 and 3 respectively; thickness of each being 1 cm. The core diameter is 2 cm. - Determine the maximum stress in the two dielectrics.
Given an analog signal with a maximum positive voltage of 3 volts and an 10-bit analog to digital converter, what will be the quantized value of an input voltage of 1.70 volts
Suppose an engineer is designing an external PCB board with an abnormally large number of programmable devices and is unsure of which protocol to choose for his hardware (DAC s, ADCs,PGAs, and Digital POTS/Trimmers)
Discuss the variation with frequency of the input reactance of a short-circuited line and its application in the determination of the location of a short circuit.
Repeat (a), but this time hold the slot width to 0.5?x and vary the slot length from ?y to 10?y. How does the transmitted amplitude vary with the slot length?
In this project we will consider the control of a synchronous generator supplying electricity to the grid.
Two machines and a lighting load are connected in parallel to a 220 V, 60 Hz line. The first machine uses 40 kW of power at 0.81 power factor lagging. The second machine uses 27 kVA at 0.93 power factor leading.
