Analog Communication is a data transmitting technique in which information signal is transmitted in analog nature. This always utilizes continuous signals to transmit data which may obtained from audio, image, video etc.

Define PAM and write down its drawbacks? The bandwidth required for transmitting is greater since the amplitude varies. What is Modulation? What happens in over modulation? Ans: In case of Nyquist rate, the sampling frequency is equal to the maximum frequency of the signal and therefore the successive cycles of the spectrum does not overlap.

Band pass filter b. Band stop filter c. Low pass filter d. High pass filter. At the receiving end b.

The position is varied in accordance with the sampled modulating signal. In PPM, synchronization is required between the transmitter and the receiver. Large bandwidth is required in Pulse position Modulation as compared to the Pulse amplitude modulation. ANSWER: To remove noise Explanation: In pulse width modulation, the width of the carrier varies with the amplitude of the modulating signal at the time of sampling. The Schmitt trigger circuit is used to remove noise in the PWM waveform. This output is the supplied further for detection of the original information.

Multiple Choice Questions and Answers on Analog Communication (Part-4)

The sampling rate of a signal should be higher than the Nyquist rate, to achieve better sampling. If this sampling interval in Differential PCM is reduced considerably, the sampleto-sample amplitude difference is very small, as if the difference is 1-bit quantization , then the step-size will be very small i. As the sampling interval is reduced, the signal correlation will be higher. The Delta Modulator comprises of a 1-bit quantizer and a delay circuit along with two summer circuits. Following is the block diagram of a delta modulator. The output quality of the waveform is moderate.

И вот эти два интеллектуала, казалось бы, неспособные на вспышки иррациональной влюбленности, обсуждая проблемы лингвистической морфологии и числовые генераторы, внезапно почувствовали себя подростками, и все вокруг окрасилось в радужные тона. Сьюзан ни слова не сказала об истинной причине своей беседы с Дэвидом Беккером - о том, что она собиралась предложить ему место в Отделе азиатской криптографии. Судя по той увлеченности, с которой молодой профессор говорил о преподавательской работе, из университета он не уйдет. Сьюзан решила не заводить деловых разговоров, чтобы не портить настроение ни ему ни. Она снова почувствовала себя школьницей. Это чувство было очень приятно, ничто не должно было его омрачить.

Отказ Хирохито… - Нам нужно число, - повторял Джабба, - а не политические теории.

Это цена, которую приходится платить за известность. - Действительно.  - Клушар вздохнул с видом мученика, вынужденного терпеть всякий сброд.
