Internal noise in communication, i.e. Which of the following statements describes what will happen as student Y moves? B. From equation (2), we see that the square of the rms noise voltage is proportional to the absolute temperature of le resistor, the value of the resistor, and the bandwidth over which it is measured. which of the following statements correctly describes the substance with the formula KI? 1. Expert Answer . External noise cannot be reduced except by changing the location of the receiver or the entire system. Internal noise on the other hand can be easily evaluated Mathematically and can be reduced to a great extent by proper design. An example of such a discontinuity is the contact between the copper lead and the semiconductor materials. As already said, because of the fact that internal noise can be reduced to a great extent, study of noise characteristics is a very important part of the communication engineering. However, this noise is inversely proportional to the frequency. Important Solutions 1. Physical noise is interference in our environments, such as noises made by others, overly dim or bright lights, spam and pop-up ads, extreme temperatures, and crowded conditions. A. Isolation transformer. Thermal noise or white noise or Johnson noise 2. The analysis of thermal noise is based on the Kinetic theory. B. C) Sound shadow is used to detect location of sounds that are far away. What term best describes a louder version of a vesicular sound that can be heard over lung ... What term is used to describe a continuous type of adventitous lung sound heard loudest over the neck of the patient with upper airway obstruction? Atmospheric noise accordingly consists of spurious radio signals with components spread over a wide frequency range. Which one of the following statements best describes the concept of sound intensity? Man-made noises or industrial noises.

Accordingly at a given receiving point, the receiving antenna picks up not only the signal but also the static from all the thunderstorms, local or remote.
