determine the frequency response for the LTI system specified by the LCCDE y[n] - 0.8y[n -1] = x[n]. Plot the magnitude response and phase response for -pie < or equal omega < or equal pie, and determine if this system is a low pass filter or a high pass filter.
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
what is the annual value to the plant owner of a 1% increase in the capacity factor of a 1,200-MWe nuclear power plant, in $/year. For example, assume the plant capacity factor increased from 0.875 to 0.885. Disregard the minor effect of capacity ..
Shuffle a deck of cards and pick two cards at random. Observe the sequence of the two cards in the order in which they were chosen. (a) How many outcomes are in the sample space (b) How many outcomes are in the event that the two cards are the same ..
A 75 ohms lossless air transmission line at 3 GHz is terminated in a load of (300-j400) (a) What is the load reflection coecient (b) Determine the impedance at 2.5 cm, 5.0 cm, 7.5 cm and 10 cm from the load.
If the voltage across a capacitor is a square wave, predict the resulting current waveform (draw the voltage and current waveforms). Repeat the process when the voltage across the capacitor is a sine wave.
Analog data having highest harmonic at 30 kHz generated by a sensor has been digitized using 6 level PCM. What will be the rate of digital signal generated
A 20 uF capacitor has a voltage of 12V across it at t=0. If a constant current of 4mA flows through the capacitor in the non-passive direction, how long will it take for all of the energy to be drained from the capacitor
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
An ordinary broadcast television channel has a bandwidth of 6 MHz. How many FM radio stations (with a bandwidth of 200 kHz each) could be accommodated in one television channel using FDM
the project manager on a development project working on a new line of laptop computers. The project has been broken down into the following modules: Power supply, Processor and motherboard with RAM, I/O circuit board
Calculate the intensity transmission coefficient T1 for the following interfaces, assuming that the ultrasound beam is exactly perpendicular to the interface: muscle/kidney, air/muscle, and bone/muscle.
Design a buck converter to produce an output voltage of 18 V across a 10- load resistor. The output voltage ripple must not exceed 0.5 percent. The dc supply is 48 V. Design for continuous inductor current.
