You are designing a reconstruction filter for a CDplayer. The filter is to have less than 1 dB ripple in thepassband compared to the response at DC. The passband is toextend to at least 16 kHz. In addition, the stopbandattenuation is to be at least 65 dB, starting at the Nyquistfrequency of 22.05 kHz. The complexity of the filter shouldbe minimized. Sketch the filter specification (amplitude vs.frequency). Which filter family would you expect would bebest suited for this application?
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which spherical radius is 40cm. Estimate the worst case variation in film thickness between the center and edges of the wafer for an evaporated aluminium 1micro meter t..
Determine which waveform in each pair is lagging: a) 6 cos(100πt-1000) and -6 sin (2π60t+1300)b) cos(10t-1000) and - cos(t-1000) c) cos (50πt - 1000) + cos (50πt - 200) and 9 cos (100πt - 200)
an electrical transformer dissipates heat equivalent of 3000 kW/h. the inlet and outlet temperatures of the cooling water are 55C and 15C respectively. calculate the mass of the cooling water in a minute.
A Technician is send to Residential House,and theHome-Owner complains that he doesn't have Emergency-Heat.However,when the Technician arrive the A ir Condition works &Heat works,but the Emergency-Heat still doesn't come on.
A three phase transformer is constructed from three 3kVA transformer. Secondaries are wired in Delta configuration with a balanced load. What is the maximun combined power that can be delivered to the load
Design a 3rd order Butterworth High-Pass filter with a Fc of 2kHz and a passband gain of 2. Find the gain and critical frequencies of each individual stage. Plot the gain portion of the bode plot.
A bus in a balanced three-phase power system has a three-phase capacitor bank that supplies 1200 kVAR. In parallel with the capacitor bank is a three-phase load that draws 3500 kW at a power factor of 0.707 lagging.
How much stator referred „external? resistance per phase should be connected in the rotor
Consider the hypothesis that an isolated hair cell (the sensory cell within the cochlea) can be modeled as a linear system when a pure acoustic tone is the input and the rate of neural firing is the output. Answer the following questions about the..
Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the following. Find the temperature at the final state.
How to calculate the transient time need for the simple passive low pass filter Why it needs the time more then 5-Tau (RC) to become a steady state
When a certain perfect gas is heated at constant pressure from 15 oC to 95 oC, the heat required is 1136 kJ/kg. When the same gas is heated at constant volume between the same temperatures the heat required is 808 kJ/kg.
