a Three phase to single phase converter employs a 6 pulse bridge circuit. This device is fed from 400V,50 Hz supply through a delta/stare transformer whose per phase turns ratio 3:1. Foran output frequency of 2Hz, the load reactance is w0L =3ohm. The load resistance is 4 ohms.The commutation overlap and tyristor turnoff time limit the firing mode to 1650.Compute (a) peak value of rms output voltage (b) rms output current (c) outputpower
Assume all that youhave a single 1nF capacitor, any number of op amps,and any numberof resistors. Design a circuit that has a port impedance of1uF.
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
Design a combinational circuit that accepts a 4-bit number and generates a 3-bit binary number output that approximates the square root of the number. For example, if the square root is 3.5 or larger, give a result of 4.

Compare the noise floor in dBm with the GSM system (BW= 200 kHz) used by the European cell standards (available today in the US thru the AT&T acquired from the Cingular systems) assuming the same noise figure (NF) of 10 dB for the same receivers.
Let x[n], y[n] and w[n] denote three finite-lenght sequences of lenghts N, M, and L, respectively with the first sample of each sequence occuring at n=0. What is the lenght of the sequence x[n] * y[n] * w[n]
