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.
The manufacturers of the tank described in Problem would like to design another model, with twice the capacity of the one described in figure. The ratio of height to diameter must
'Electric drives' is a term used to describe DC and AC electric motors that provide continuous rotarmotion. They are often controlled by 'electronic drivesystems' designed to contr
Define Shifting and Reversing – Linear System? The signal x[n - m] is said to be time-shifted by m samples, where m is an integer. If m is positive, the shift is to the right (
What is the purpose of carry (c) flag and zero (z) flag? Carry flag conatins the carry after addition or borrow after subtraction. This carry flag also shows error conditions,
Explain Loads - Generation and Absorption of Reactive Power A load at 0.95 power factor implies a reactive power demand of 0.33 kVAr per kW of power. When planning a network, i
1. Introduction : Theory: Frequency is the number of occurrences of a repeating event per unit time. It can also be defined as the number of repetitions (cycles) of a w
Evaluate the form factor: For the saw tooth wave illustrated in Figure, find out the form factor. Figure: Saw Tooth Wave Solution Time period of given wave i
Q. A four-pole dc generator is lap wound with 326 armature conductors. It runs at 650 r/min on full load, with an induced voltage of 252 V. If the bore of themachine is 42 cmin dia
Q. For a transmission-line model that includes only the series impedance Z, sketch phasor diagrams for: (a) Lagging power factor load. (b) Leading power factor load.
Q. Explain Solid-State Control of DC Motors? Dc motors, which are easily controllable, have historically dominated the adjustable-speed drive field. The torque-speed characteri
