1. A PCM system uses 8 bits per sample and the analog signal is limited to 4.3 kHz. The PCM data is transmitted using (a) BFSK and (b) ASK. Determine the bandwidth required for transmission in each case. Assume that r = 0:55.
What is the effect of overheating on the life of an electric insulator? An insulator is designed to withstand amount of heat. However, when an insulator is overheated so dielec
Suppose that a video signal, having W = 5 MHz, is transmitted via FM with f = 20 MHz. For 1/100 ≤ B/fc ≤ 1/10, determine the bounds on the carrier frequency. Use WFM ∼ = 2( ω + 2W
Q. Methods for speed and torque control of induction motors? The following are methods available for speed and torque control of induction motors. • Pole-changing method
An induction motor takes 350 kW at 0.8 power factor lagging while driving a load. When an overexcited synchronous motor taking 150 kW is connected in parallel with the induction mo
Compute the total capacitance with parallel connection: Three capacitors C 1 , C 2 and C 3 contain capacitance 20 μf, 15 μf, 30 μf, respectively. compute: 1. Charge on ea
Mention how do the DIV & IDIV instructions differ in their functionality DIV: Unsigned numbers division and IDIV: Signed number division.
One battery having of four cells, connected in series. Emf of each cell is 1.45V and internal resistance of 0.04Ω. if a load resistance of 5Ω is connected to the battery, draw the
Q. Show Maximum Power Transfer? In order to investigate the power transfer between a practical source and a load connected to it, let us consider Figure , in which a constant v
A periodic voltage consists of sinusoidal pulses having an amplitude of 150 V (SEE DIAGRAM BELOW). Use Fourier Series Expansion to calculate: 1. the amplitude of the DC co
