1. Tell me what you know about how a tenth-order lowpass Chebyshev filter is implemented. Your discussion should include the center frequencies and Qs of the stages.
2. To get a fast roll-off and a linear-phase response, somebody has cascaded a Butterworth filter with an all-pass filter. Tell me what each of these filters does.
3. What is an MFB filter and where is it used?
Choose an application in business or industry that uses RL or RC circuits in its operation.
Attenuation of received power with change in transmission frequency and distance between the antennas
Gaussian white noise, perfectly band-limited to 0-10MHz, is passed through a perfectly rectangular filter of bandwidth 18 kHz, gain 3 dB, and center frequency 455 kHz. If the RMS voltage of the input noise is 1 volt
AC power supply is provided to our homes from grid station, but there are many home appliances that are operated by DC.Justify how they will operate while AC main supply is provided but we have needed DC to operate them.
The manufacturer ships 100 boxes via commercial airliner from Los Angeles to New York. The distance between the two cities is 2,500 miles by air, and the airliner flies at a speed of 400 mi/h. What is the data transmission rate between the two cit..
Write the mathlab program to plot the modulation index necessary to keep the Vdc constant at 1200v when the input power factor angle is varied from -60 degrees to 60 degrees.
Incremental Update. Typically, after every hop at least one packet header field (e.g., a packet's time-to-live field) needs to be overwritten. Because the checksum is a simple complement of a 1s complement sum, it turns out that when, for instance..
A quartz window of thickness L serves as a viewing port in a furnace used for annealing steel. The inner surface (x = 0) of the window is irradiated with a uniform heat flux q;: due to emission from hot gases in the furnace.
What about the flow of energy from the resistor to the water?
A certain material being measured undergoes a strain of 3 parts per million. The strain gage has a nominal resistance of 600 and a gage factor of 2.5. Determine the resistance change in the strain gage.
At a frequency of 60 Hz, the core loss of a certain coil with an iron core is 1.8 W, and at a frequency of 120 Hz, it is 5.6 W. The peak flux density is the same for both cases. Determine the power loss due to hysteresis and that due to eddy curre..
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.
