Assume x(t) has a bandwidth of 40 kHz.
1. What is the minimum sampling rate for this signal?
2. What is the minimum sampling rate if a guard band of 10 kHz is required?
3. What is the maximum sampling interval for the signal x1 (t) x(t) cos(80,000πt)?
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal)
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
An amplifier has an open-circuit gain of-60, an input resistance of 8 k Ω, and an output resistance of 2 k Ω. A microphone transducer source is connected to the amplifier Input and has a source output resistance of 2 k Ω, and a speaker load is connec..
An RC circuit with a time constant T = 30 msec has reached a steady state of 2 V at time t = 0. The circuit is then suddenly switched to ground (0 V). Calculate the time required for the voltage to fall to 1 V.
(a) Determine the rms value of the fundamental and each harmonic. (b) Write down an expression to represent the complex voltage waveform if the frequency of the fundamental is 31.83 Hz.
If it is known that an electric dipole is located at the origin andthat its E-field at the point P(2[m], 30°, 90°) isE=4âθ[V/m],find the magnitude and direction of the dipole moment p.
1 a discrete memoryless source has a symbol alphabet of a 10. determine the upper and lower bounds on its entropy. 2
Consider the function F = x · y + x(not) · z. a) Expand the function to its canonical or standard sum of products (SOP) form. b) Express the function in its canonical or standard product of sums (POS) form.
Why do geothermal heat pump systems work better in cold climates than air-source systems?
