Question 161. What is the category of data transmission if the binary pulse is maintained for the entire bit time?
Question 162. It is a system where the digital signals are placed directly on the coaxial cable.Question 163. A scheme in which several channels are interleaved and then transmitted together is known asQuestion 164. A signaling system in which each letter of the alphabet is represented by a different symbol is not used becauseQuestion 165. The basic modulator and demodulator circuits in PSK are Question 166. Pulse – amplitude modulation signals are multiplexed by usingQuestion 167. It is the thermal noise power normalized to 1-Hz bandwidthQuestion 168. The slope of the analog signal is greater than the delta modulator can maintainQuestion 169. It is the transmittal of digitally modulated analog signals (carrier) between two or more points in a communications system.Question 170. A pulse modulation technique as the width of a constant amplitude pulse is varied proportional to the amplitude of the analog signal at the time the signal is sampled.
