(a) Design the schematic circuit diagram of a digital filter (FIR).
(b) How can an Si shaped pulse response be trimmed by means of a schematic circuit.
(c) What role do the filter coefficients of a digital signal (FIR) play?
The voltage across a 5-Ω resistor is as indicated. - Find the sinusoidal expression for the current. In addition, sketch the v and i sinusoidal waveforms on the same axis.
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.
A 230kVA, 2300/230V, 60 Hz, step-down transformer has the following parameters. RH =1.2-ohm, XH =3-ohm, RL =12m-ohm, XL =30m-ohm, Rh+c=2k-ohm, , Xm =1.8k-ohm. If the transformer operates at half load with unity power factor
A 10Ω resisitor is connected across a 120-V rms sinusoidal 60-Hz line. What value is the closest to the average current flowing in the resistor between t=0 and t=.0042 sec
question 1part agenerate and plot a sampled sine wave with fs 8khz of 4 seconds duration with frequency omega0 pi10
The characteristic equations for a D flip-flop determine that the output Q is updated to either 0 or 1 after each clock cycle. A loadable D flip-flop has one additional input Load that allows data to be stored in the flip-flop for more than a sing..
Why link is provided in neutral of an ac circuit and fuse in phase of ac circuit?
What happens to the spectrum and time domain output when the laser is mode-locked? Why is a four-level system normally more efficient than a three-level system? What are the primary characteristics of an argon laser?
Determine the nodal voltages for the networks of given figure. - Find the voltage across each current source.
A sinusoidal signal with frequency known to be less than 1 kHz is sampled at 600 Hz. and appears as a 150 Hz signal. The sample rate is changed to 550 Hz, and the apparent frequency of the sampled signal shifts to 100 Hz.
The output of a communication channel is Y = X + N where X and N are independent, zero mean, random variables. X represents signal and N is noise. (a) Find the correlation coefficient between the input X and the output Y.
