Sampling frequency and bit rate of transmissionThe output of a video surveillance camera is an analog signal with a bandwidth that extends from 0 Hz to 1.5 MHz. The signal is sampled at 1.2 times its Nyquist rate.
The resulting PAM signal is converted to 6 bit digital words with an analog to digital converter and the words are transmitted serially over a twisted pair used as the cable for data transmission.
a. What is the sampling frequency?
b. What is bit rate of the transmission on the twisted pair?
c. If the digital outputs of three identical video cameras are combined onto a single cable using time division multiplexing, what is the bit rate on the cable?
State Carson's rule for bandwidth estimation. What does it reduce to for NBFM and WBFM and d erive an time domain expressionfor the output xd(t) of the system
Calculate the %age second harmonic distortion present in the amplifier's output for a sinusoidal input of 10 mV r.m.s.
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
The magnetic tape recorder uses linear analog to digital encoding. Telephone systems use non linear analog to digital conversion. Explain the difference.
Evaluate the size of the solar PV system and Sizing a Solar PV System - What is their monthly average energy use?
What is the problem you are investigating and explain the issue, its history, the impact it makes locally
Finding the periodicity in N of the discrete time signal x(n) = Cos(3pi*Ts.n + pi/4) and then plotting the discrete signal. From this the condition on the sampling period is determined
