Discrete Systems and Digital Signal Processing Looking for a step by step solution to the following question,
y(n) - .6y(n-1) + .6y(n-2) = 0, y(-1) = 0, y(-2) = -1
What is the output do to the given initial conditions
If AC is a sine wave and DC is a straight line, what would the wave look like on a graph if they combine. How/what to calculate to get this new waveform.
Sketch a time diagram similar to Figure 3.22 illustrating what happens when a frame gets lost between the sender and the receiver. It should be clear from your diagram how the protocol handles this situation.
Two dc motors are compared. the first one is a 4hp dc motor which draws a current or 0.7A when the field is connected to a 150V source. the second, a 600 hp motor draws a field current of 5A when the field is connected to a 300V dc source.
Determine the requirements of the digital fiters needed and design and write the di erence equations for the digital fiters.
A certain magnetic core has a core loss of 8.4 W, of which one-third is eddy current loss, when the magnetizing field is changed 60 times a second. determine the core loss if the magnetizing field is changed only 50 times a second.
A DSP system has a sampling frequency of 800 HZ. What is the maximum frequency of the analog signal so that the aliasing would not occur
Three single phase 2400v/240v transformers are connected for operation as a 4160/240 v 3phase bank. Each transfomers has a Zeq1=1.42+j1.82 ohms and rated at 150kva
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Port B, which is connected to an LED.
Suppose that OFDM is used with 15 kHz subchannels. (Two subchannels are used as guard channels on either side of the band.) Specify an OFDM symbol rate and modulation format for each subchannel that can achieve the target rate.
Two machines and a lighting load are connected in parallel to a 220 V, 60 Hz line. The first machine uses 40 kW of power at 0.81 power factor lagging. The second machine uses 27 kVA at 0.93 power factor leading.
How would you select the right components for the integrator and differentiator. What do you think would be the limiting factor in the component parameters, and in the input signal frequency
An amplifier has a gain of 10 and follow a bandpass filter filter where the loss in the in the center of the bandpass is 0.05. What is the combined gain/loss of the two cascaded blocks at the center frequency of the filter
