Suppose we are allowed to observe a random process Z (t) t at two points in time, and t0 and Based on those observations we would like to estimateZ (t) at time where We can view this as an interpolation problem. Let our estimator be a linear combination of the two observations,
(a) Use the orthogonality principle to find the MMSE estimator.
(b) Find an expression for the mean square error of the MMSE estimator.
Design a frequency divider cicuit that will produce the following three ouput signal frequencies: 1 MHz. 800 kHz, and 100 kHz. Use 74HC160 and 74HC161 counter chips and any necessary gates. The input frequency is 12 MHz.
It is often preferred to use a FET for the RF amplifier in an AM receiver. Can you explain why?
Solve for the currents IB, IC, and IE using the fact that VBE = 0.7 V and VCE = 8 V. - Find the voltages VB, VC, and VE with respect to ground.
Calculate the resonance frequency, fo of the circuit and calculate the cut-off frequencies f1 and f2 of the circuit - Calculate the transfer function
Block diagram and equations for control system water fill, Develop a control system to fill a container with water after it is emptied through a stopcock at the bottom
Develop with MATLAB, a fuzzy control system for controlling the power of a motor (0-350 rpm) based on the supported load (0-1700 lbs) thereby that at greater load develops more power. The system must contain at least 5 rules, but preferably 7.
A 1000KVA transformer is at full load with a 0.5 laggingpower factor. If the line voltage is 500 volts at 60Hz. Find the following quanties needed to improve the power factor to 0.95 byadding capacitors in parrallel with the transformer.
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the transmitter output to the antenna
