a. Use the normalized low-pass to band-pass transformation to convert the low-pass function in the last problem. Find the locations of the bandpass filter poles.
b. Find the approximate locations of the bandpass poles for the narrow-band case, i.e., ω0 » B and sketch the pole-zero plot.
The highest frequency component of high-fidelity sound is 20 kHz. If 16 bits are used to encode the quantized signal, what bandwidth is needed as a minimum for the digital signal?
Determine the location of the shear center O of a thin-walled beam of uniform thickness having the cross section shown
There are two printers and two I/O ports available in a system. Process A is using an I/O port and is waiting for a printer. Process B is using a printer. Process C is using a printer and is waiting for an I/O port.
Suppose a filter has a transfer function. - Find the noise equivalent bandwidth of the filter.
What happens to the spectrum and time domain output when the laser is mode-locked? Why is a four-level system normally more efficient than a three-level system? What are the primary characteristics of an argon laser?
A 20-m3 tank contains nitrogen at 23 C and 600 kPa. Some nitrogen is allowed to escape until the pressure drops to 400 kPa and the temperature to 20 C. Determine the amount of nitrogen gas that has escaped in kg. How much in this in Kmoles
Steam enters a reversible, adiabatic (isentropic) turbine at 8 MPa and 550 oC with a mass flow rate of 3.6 kg/sec. The pressure of the steam flow at the turbine exit is 250 kPa. Neglect the changes in potential and kinetic energies of the flow thr..
The current density in a region isJs = xyâz[A/m2], wherex and y are specified in meters. Find the currentI flowing towards increasing vales of z throughthe surface -1
derive the design equations for R1 and R2 for each circuit. If Z0 = 50 Ω, compute R1 and R2 for 3, 10, and 20 dB attenuators of each type.
Create 2 equations with 2 unknown variables. For example, one equation would be ax + by = c and the other equation would be dx + ey = f where x and y are the variables and a, b, d, and e are coefficients for the variables and c and f are numbers.
An ideal n+/p diode has only the quasi neutral p region of length L illuminated with light such that GL electrons/cm3-s are generated uniformly throughout the region. There is no photo-generation occurring elsewhere in the diode. Derive the curren..
Electrons and holes are moving in a uniform, onedimensional electric field E = +2500 V/cm. The electrons and holes have mobilities of 700 and 250 cm2/V · s, respectively. What are the electron and hole velocities
