Suppose the maximum fade duration over a radio channel is 0.001 ms. Assume that all the bits are in error when a signal encounters a fade. What is the maximum number of consecutive bits that are in error for a transmission through this channel if the data rate is 10Kbps? If the data rate is 11 Mbps?
Determining how to use the function fft to find the DFT coefficients X[k] of x[n] in Matlab. Also, how would you plot the magnitude of X[k] in Matlab?
What is the peak frequency deviation of the FM signal? What is the FM improvement in dB?
Calculating peak frequency deviation and Carson's rule bandwidth, A baseband signal has a frequency range from 50 Hz to 15.0 kHz. The signal is transmitted using frequency modulation. The FM transmitter has a modulation constant of 100 kHz per vol..
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
Maximum Likelihood to get the above parameters i.e. u0 and var. Now from these 999 points, I take one point out (lets call it i) and add a new point (lets call it j). What will the new mean and variance be?
Design a 2-digit 24 second "shot-clock" countdown timer with pushbutton controller.
The magnetic tape recorder uses linear analog to digital encoding. Telephone systems use non linear analog to digital conversion. Explain the difference.
What RF bandwidth is required to send the data using QPSK? If the RRC filters in the transmitter and receiver are replaced with ones that have ? = 0.20, what are the new RF bandwidths in parts (a) and (b)?
Using the Nth order term only of the transfer polynomial, find the Nth order relationship for the Nth order products.
