1. Draw the four brick wall responses. Identify the passband, stopband, and cutoff frequencies of each.
2. Describe the five approximations used in filter design. Use sketches as needed to show what happens in the passbands and stopbands
3. In digital systems, filters need a linear phase response or maximally flat time delay. What does this mean, and why is it important?
1.How do you compare PCM with PWM and PPM?2.A 8-bit ADC with 5 volt full scale voltage samples an analog signal at 1 kHz. Find the speed of the binary information at the output of the ADC.
Plot the reconstructed waveform for each case.
When output characteristics (Ids versus Vds) plotted for n-channel JFET at Vgs made positive with respect to source , What will be expected at the output characterics (current)
In an amplifier circuit, why do we need to bias the MOSFET atan operating point What would happen if the signal peak amplitudewas smaller than 1 V, the transistor had Vto=1 V and we biased the transistor at Vgsq=0
Design combination circuits that generates the -ve of a give 4-bit +v signed number, e.g. if it is +2 the circuit will generate -2 and if it is -2 the circuit will not change it. assuming that the signed number is in 1's complement representation.
What pressure would you expect for 5 ft of water?
Define induction motor and explain its principal of work
D rectangular resonator. Write a 3D FDTD algorithm using Equations (4.18) and (4.19) in a 100 × 50 × 20 m box with perfectly conducting walls.
For a randomly chosen day, find the unconditional probability that exactly two defectives are observed in the sample.
What is the common-mode voltage gain of Fig. 15-37? If a common-mode voltage of 20 μV exists on both bases, what is the common-mode output voltage?
