(a) Design and simulate an AM tuner according to Illustration 168. You will have to set the sampling rate at roughly 2 MHz and the blocklength at at least 1024.
(b) Afterwards create a realistic AM signal in the medium wave range from 525 to 1645 kHz which you superimpose on noise. Try to retrieve and demodulate the corresponding AM signal. Tip: make sure there is a favourable relationship between the signal and the level of noise.
Design a D.T. FIR filter to only pass a band of frequencies 20 kHz wide from the frequencies between 10 kHz and 30 kHz. The center frequency of the band lies at 20 kHz and the sampling frequency is 200 kHz. Use the Hamming window.
two factory produces identical clock production of first factory consist 10000 clock in which 100 are defective the
The photoelectric threshold wavelength for Tungsten is 2300 Å. Find the energy in eV of the emitted electrons from the surface by ultraviolet light of wavelength 1800 Å.
What is the minimum value of power p for which the XOR problem is solved? Assume that p is a positive integer. What is the result of using a value for p larger than the minimum?
If the power factor is raised to unity, how many more kilowatts can alternator supply for the same kVA loading ?
Calculate the load power under this matching condition.
A voltmeter is specified to have an accuracy error of ±0.1% of full-scale on a ±1V scale. If the meter produces a reading of 0.323VDC, what is the minimum and maximum DC levels that might have been present at the meter's input during this measurem..
Calculate: i. The A, B, C, D constants of the line. ii. The characteristic impedance of the line. iii. The sending-end voltage iv. The sending-end current. v. The sending-end power factor. vi. The sending-end power. vii. The power loss in the line..
if we have an amplifier whose spec. is 2nV/rtHz and the bandwidth of the amplifier extends from 100Hz to 10kHz, and the gain of the amplifier is 5, how much noise should we expect at the output of the amplifier
It is desired to run the motor in the previous problem with a power factor of unity. To achieve this, a capacitor C is connected in parallel across the motor, which results in a circuit like that shown in Fig. 2.13. Calculate the value of C to ach..
what is transmission velocity and how it is different from drit velocity. Drift velocity the actual (physical) velocity of electrons along the wire.
Six light bulbs are connected in parallel across 120 V. Each bulb is rated at 75 W. What is the current through each bulb, and what is the total current?
