Construct and label carefully each of the following signals
y(t)=x1(4-t/2)
Design a Chebyshev Type-1 digital low-pass filter on A4 sheet to satisfy the following
constraints:
X dB ripple in passband 0 ≤ ω ≤ 0.2π
Y dB attenuation in stopband 0.45π ≤ ω ≤ π
Use Bilinear Transformation assuming T = 1 sec.
Draw the circuit and write a program for 8085 and 8255 to monitor the temperature of a room and if it exceed 100oC then water sprinkler should be on
The output power of a shunt motor running off a 250v supply is 16kw. calculate the value of the starter resistance to limit the starting current to 1.5times the full-load current if the full-load efficiency of the motor is 80% and the resistance of the armature circuit is 0.2ohms. Neglect the shunt current
Describe the three types of fiber misalignment which may contribute to insertion loss at an optical fiber joint. A step index fiber with a 200 μm core diameter is butt jointed. The joint which is index matched has a lateral offset of 10 μm but no longitudinal or angular misalignment. Using two methods, estimate the insertion loss at the joint assuming the uniform illumination of all guided modes.
Classify the following signal as energy signal or power signal. Find the
normalized energy or normalized power.
(i) sin 2t + 3 cos 4t
Design a digital low-pass Butterworth filter on A4 sheet to satisfy the following
