a. Consider the design of an MMSE equalizer for a multipath channel whose output is of the form
b. Obtain the optimum tap weights for a three-tap MMSE equalizer and at a SNR of 10 dB and b = 0:5.
c. Find an expression for the MMSE.
A coil has an inductance of 400 mH and aresistance, RL, of 10 Ω. The coil is connected in series with a 100 Ω resistor Racross a 240V - 50Hz supply voltage V. Sketch the circuit diagram and phasor diagram; take V as the reference phasor.
Show that a BCD ripple counter can be constructed from a four-bit binary ripple counter with asynchronous clear and a NAND gate that detects the occurrence of count 1010.
A long wire carrying a 5.0 A current perpendicular to the xy-plane intersects the x-axis at x = -2.0 cm. A second, parallel wire carrying a 3.0 A current intersects the x-axis at x = +2.0 cm.
Using ideal diodes and other components, construct a circuit that provides such a characteristic. (The value of resistors is not unique.)
How can the output from a radio remote control be converted into a steady analogue signal?
An FH-BPSK signal modulated with 6kbps data has a spectrum bandwidth of 20 MHz. the BPSK signal is filtered allowing only two spectral components on either side of the carrier find the maximum number of hopping frequencies.
Design and model a car battery charger using PSpice. Suppose that the source is a commercial circuit of 240V AC at 60Hz. The battery to recharge is 12V DC.
Determine its efficiency and the torque supplied by the prime mover. Sketch its power flow diagram.
A three-stage amplifier is shown. The operating bandwidth is 500 KHz at a temperature od 25 degrees C. The output load is 1000 ohms. calculate the total NF as a number, calculate the output noise power, and calculate the output noise voltage.
A balanced Δ connected load of 15 + j9 Ω/phase is being fed by a Δ connected source. Each of the three lines feeding the load from the source has 0.5 + j0.3 Ω impedance. The voltage at the source is 400 VLL.
Plot the square-wave approximation by summing the series through the seventh harmonic.
It involves developing a function called "single_phase_transformer_tests" that can work on user input data to generate the transformer voltage regulation and efficiency under various loading criteria.
