Explain Noise
Noise is unwanted signals which degrade the desired signal content and therefore the performance of the system. Noise might be produced either externally or internally to the system. External noise contains atmospheric interference, man-made interference, lightning, etc. Internal noises are produced by the components and devices used in the system.
Q. The circuit shown in Figure is the equivalent circuit of a field-effect transistor (FET) amplifier stage. (a) Determine the y-parameters. (b) For values of µ = g m /g d >
There is a limitation on the size of data. Most Microprocessor does not maintain floating-point operations.
HT Metering The following type of meters is generally used for HT consumers: Trivector Meter, Bivector Meter, and Summation Meters. Trivector Meter
Explain Limit Signal Spectrum to Prevent Aliasing? The sampling frequency should at least be two times that of the highest frequency in the incoming signal to avoid aliasing. T
Given the block diagram of a synchronous counter shown in Figure (a), draw the timing diagram for the first input pulses, with Q 1 , Q 2 , and Q 3 initially at 0.
Electrical power Power P in an electrical circuit is given by the product of potential difference V and current I. The unit of power is the watt, W.
Mathematical relationship between the induced e.m.f and the network Faraday noted that the e.m.f induced in a loop is proportional to the rate of change of magnetic flux by it:
Q. In plotting a hysteresis loop the following scales are used: 1 cm = 400 At / mand 1 cm=0.3 T. The area of the loop for a certain magnetic material is found to be 6.2 cm 2 . Calc
Triac As the name suggests TRIAC is advice which has three electrodes and works on AC. The three terminals of triac are MTI ( Main Terminal ) MT2 ( Main terminal ) an
a) Give four features that were traditionally reserved to RISC architectures? b) Determine the overall throughput for 21 sequential instructions assuming a four-stage pipeline a
