You are designing a reconstruction filter for a CD player. The filter is to have less than 1 dB ripple in the passband compared to the response at DC. The passband is to extend to at least 16 kHz. In addition, the stopband attenuation is to be at least 65 dB, starting at the Nyquist frequency of 22.05 kHz. The complexity of the filter should be minimized. Sketch the filter specification (amplitude vs. frequency). Which filter family would you expect would be best suited for this application?
Calculate Vout (f0), Vout (3f0), Vout(5f0), and Vout(7f0) of the frequency spectrum of a triangle wave (A = 10 V and T = 1 ms) passed through a low-pass R-C filter (R = 10 k-ohm and C =5 nF).
Estimate the propagation delays of implementations (1), (2) and (3) using typical propagation delay data in the timing specifications of the logical gates of CD4000 family. Take the average propagation delay for 1-0 and 0-1 output transitions.
A force Farrowbold applied to an object of mass m1 produces an acceleration of 3.40 m/s2. The same force applied to a second object of mass m2 produces an acceleration of1.60 m/s2. If m1 and m2 are combined into one object
Common drain amplifier config. uses NMOS device with a nominal load of 2kΩ. If gain of amplifier is 0.90 V/V, what is output resistance. If device has k'n W/L=8mA / V2, what is the bias drain current So need to find Ro and ID.
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
Alfredo deDarke sleeps with a 7.5-Watt night light bulb on. He turns it on before getting in bed and turns it off 8 hours later. a. Determine the amount of energy used during one evening in units of kiloWatt*hours.
A process worker received an electric shock when she attempted to turn off a conveyer control. The toggle switch controlled the power to a variable speed drive. An examination found that dust had accumulated on the toggle switch. Moisture on the ..
If the LSB signal is transmitted through a channel that only introduces a 0.3 ms delay, and the oscillator at the LSB receiver produces a local carrier 2 cos(2 pi fct), determine the receiver output signal y(t).
The following tests are performed on a single phase transformer rated 30/6.3 KV , 10 MVA , 50 HZ i- Short circuit test with L.V side short circuited and measurement made on H.V side I = I full load , V = 2700 V , P 80 KW
A radially dependent surface charge is distributed on an infinite flat sheet in the x-y plane and is characterized in cylindrical coordinates by surface density ps = p0/p, where p0 is a constant. Determine the electric field strength, E, everywher..
Design a circuit using a thermister in a Wheatstone bridge and a comparator to turn on a furnace when the temperature drops below 70 ?F. Use real components selected from an online distributor, such as Digi-Key or Mouser
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
