A simple low-pass discrete-time filter is characterized by the following linear difference equation:
y[n] = f y[n-1] +(1- f) x[n] , with 0 1
Draw and clearly label an adder-gain-delay diagram for the filter.
using the same difference equation from above.Unit Impulse Response and Unit Step Response
Calculate and plot the unit impulse and the unit step responses of this filter, for n from 0 to 10, for f = 0.1, 0.2, 0.5 and 0.9. What are the limiting values (the values as n becomes large) of the responses?
What would be the minimum sample rate needed to adequately acquire an EKG signal Note that this problem is not as simple as it appears to be, because while the fundamental frequency may be relatively low, artifacts in the EKG may be at frequencies..
The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
Received power of half-wave dipole antennas, Assume that two antennas are half-wave dipoles and each has a directive gain of 3dB. If the transmitted power is 1W and the two antennas are separated by a distance of 10 km, what is the received power?
A 4 MHz time-harmonic uniform TEM plane wave that is traveling through a lossy nonmagnetic medium has an amplitude that attenuates by 20% for each meter of propagation. The electric field of the wave leads the magnetic field by 35°
Write a short essay on your genre (ACTION) and its importance to the film canon. Use specific examples of films that illustrate its importance (you don't need to limit yourself to films you watched for this class).
Why developing software for wireless devices is challenging? List and briefly describe the two (2) reasons given in your textbook for why developing software for wireless devices is challenging.
Research the recent history of gasoline pricing in your area, and attempt to relate any fluctuations you observe to documented supply and demand factors outlined in our book. Be sure to cite any references used.
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
Reduce the equation to the slope-intercept form and give the slope and the y-intercept.
The average voltage across the load when the triggering angle is 140 degrees. Keep in mind that the conduction is incomplete when the triggering angle is greater than 140 degrees.
Design a combinational circuit with four inputs, x,y,w, and z, and four outputs: A, B, C, and D. When the binary input value in decimal is 3,5,6,9,10 or 12, the binary output value is one less than the input value, otherwise it is one greater than..
What is the maximum allowable value Xmax of X? The system is built with X-Xmax. An engineer argues that the host on the sort side of the bridge can use a minimum frame length shorter than 512 bits if they are talking to other hosts on the same sid..
