Characteristics of a filterA filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz.From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical axis) against log frequency ( horizontal axis).
a. Is this a low pass, high pass, band pass or band stop filter?
b. What is the attenuation per decade between 2 kHz and 20 kHz?
c. What is the attenuation at 4 kHz?
d. Is this an ideal filter or does it behave like a real filter?
The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
Compute and plot the correlation sequences r s1s2 (l), r s0s0 (l), r s1s0 (l) and r s2s0 (l) . Compute and plot the cross-correlation sequences and of the received signal with the template signals and s 2 (n).
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
What effect do internal capacitances in the transistor model have on practical performance of a real system? How would you use these model values to predict system performance?
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
