A waveguide load with an equivalent TE10 wave impedance of 377 must be matched to an air-filled X-band rectangular guide at 10 GHz. A quarter-wave matching transformer is to be used, and is to consist of a section of guide filled with dielectric. Find the required dielectric constant and physical length of the matching section. What restrictions on the load impedance apply to this technique?
A three phasestar connected alternator with synchronous impedance of 1+j5 ohms per phase is connected to an 11kV system. The alternator power outputis found to be 10MW and reactive power output as 3MVAr.

The power consumption of asingle-phase electric load fed from a 120 volt source representedby: P(t) = 100 (1-e-t/10) KW where t is the unit time inhours. Compute the energy consumed by the load over the period of 24 hours.
Desing a combinational circuit that accept a 3-bit numbuer and generates a 6-bit binary number output equal to the squre of the i/p number.
Suppose a recording is made of a piano performance. Lets call the analogue voltage coming out of the amplifier system as v(t) and it needs to be converted in digital signal. if v(t) is given as v(t)=10*sin(2*pi*196*t)
