(a) Which one of the four digital-to-analog conversion techniques (ASK, FSK, PSK or QAM) is most susceptible to noise? Explain your answer.
(b) Given the bit pattern 01001110, sketch the waveforms for NRZ-L, Bipolar AMI, Pseudoternary, Manchester and Differential Manchester encoding. Assume that the most recent preceding 1 bit for AMI has a negative voltage and the most recent preceding 0 bit for Pseudoternary has a negative voltage.
(c) PCM is based on the Nyquist Sampling theorem.
(i) State the Nyquist Sampling theorem.
(ii) A complex low pass signal has bandwidth of 200 kHz. What is the minimum sampling rate for this signal?
(d) What is the maximum data rate for a voice-grade line with a bandwidth of 4 kHz and a S/N ratio of 10000 to 1? Also, what is the maximum data rate if the S/N ratio is now enhanced to 50 dB?
Define Magnetic field The area around a magnet is known as the magnetic field and it is in this area that the effects of the magnetic force formed by the magnet can be detected
What are the industrial applications of the project bcd to excess 3 code converter?
short note on cumulative error
Input Output Operations Many times microprocessor has to accept data from input port and send data to output port to interact with the real world. Input port is tri st
Q. A four-pole dc generator is lap wound with 326 armature conductors. It runs at 650 r/min on full load, with an induced voltage of 252 V. If the bore of themachine is 42 cmin dia
Q. A magnetic force exists between two adjacent, parallel current-carryingwires. Let I 1 and I 2 be the currents carried by the wires, and r the separation between them. Making u
