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.
Q. Can you explain about Multiple Poles? Let us consider that F 1 (s) has all simple poles except, say, at s = p 1 which has a multiplicity m. Then one can write When
Q. What do you mean by Phase Sequence? It is standard practice in the United States to designate the phase A-B-C such that under balanced conditions the voltage and current in

FIGURE shows a pneumatic circuit diagram used for air supply and exhaust in an automatic control system. (a) Name all symbols (including pipelines) used in the system. (b) N
Voltage and Frequency Control Methods In this control method the ratio of voltage to frequency is kept constant so that the flux remains constant. The voltage at varia
If a high resolution emcoder is used for position control, will the number of pole count in the DC motor be matter? What is the requirement for the DC motor in order to work with h
Q. A two-pole rotating machine with a singly excited magnetic field system as its stator and a rotor (that carries no coil) has a stator-coil inductance that can be approximated by
Q. The energy stored in a 2-µH inductor is given by w L (t) = 9e -2t µJ for t ≥ 0. Find the inductor current and voltage at t = 1 s.
Q. A 5-kVA, 480:120-V, two-winding, 60-Hz, single-phase transformer has an efficiency of 95% while delivering rated load at rated voltage and 0.8 power factor lagging. This transfo
