An analog signal of maximum frequency component of 10 kHz is applied at the input of a PCM system with an uniform quantizer having 32 levels. What will be the Transmission bandwidth of the PCM system?   Please answer only if you are confident.

Q.1 (Fill in the Blank): ________________ is the conversion of discrete-time continues-valued signal into a discrete-time discrete-valued (digital) signal?

A digital communication link carries binary-coded words representing samples of an input signal,                                        xa(t)=3cos⁡(600πt)+2cos⁡(1800πt)The link is operated at 1,000 samples/s.    (a) What is the folding frequency?   (b) What is the Nyquist rate for the signal  xa(t)?   (c) What are the frequencies in the resulting discrete-time signal x(n)?   (d) Will there be any aliasing here?   (e) Which frequency will alias to what frequency

Derive the transfer function of the system.

A digital data will be transmitted over an analog transmission medium that has amaximum bandwidth of 1.4MHz with SNR=26.2 dB.a) What is the maximum data speed that can be achieved in this system?b) If you consider only the white noise, what is the minimum signal power required withinthis transmission system?c) How many signaling levels should be used to reach to the data rate that you calculated inpart (a)?

Type your question here For the system shown below: a) Find Vrms of noise at system output. b) If ?(?) = 5 cos 2000?? volt, find signal-to-thermal noise ratio at system input & output, to calculate noise power assume the following values of system bandwidth: 1- Entire frequency band 2- -3dB bandwidth 3- Equivalent noise BW 4- BW=100 kHz

Type your question here When the input to a given system audio is (4 cos 800 ?? + ??? 2000??) ??, the measured frequency component at 600 ??? is 1mv. Represent the amplifier output – input characteristic by ?? = ?1?? + ?2?? 2 and calculate the numerical values of ?1 and ?2 from the data given.

Consider a telephone line initially noiseless channel having bandwidth and signal level determined by the network engineer. Calculate maximum data rate. After certain distance the channel becomes extremely noisy, so that the noise is strong which faints the signal .Calculate the capacity of the channel.
