FINAL ASSIGNMENT REVIEW QUESTIONS 2 Final Assignment Review Questions 2.1 Differentiate between an analog and a digital electromagnetic signal. Analog signal is known not the quality consistently by rolling out an improvement in the properties of variables such as liquid levels, fluid pressures, current changes or electrical voltage. Digital signal dependably have discrete qualities. Variety in analog signal is because of time and takes after non-direct electrical signal. The digital signal experiences the changes in individual steps and involves beats and digits. 2.2 What are three important characteristics of a periodic signal? Period (or frequency), amplitude and phase. Every single periodic signal can be separated into different signals... most generally sine/cosine waves, yet there are others as well. These parts will each have their own frequency, amplitude and phase that consolidate into the original signal. A signal all alone does not have a phase unless you give some reference signal to compare it to. Generally, this correlation signal is suggested by the connection of your specific event. When you decompose a periodic signal into parts, then again, it is quite often suggested that the phase of every segment is in reference to the basic segment (So the major has phase 0, while the others have phases referenced to that). This is done particularly so that every segment will join to make the original signal. 2.3 How many radians are there in a complete circle of 360 degrees?

FINAL ASSIGNMENT REVIEW QUESTIONS 3 A radian is a summed up unit of measure that portrays the arc length of a circle between two lines that share the origins origin, an approach to express that length as far as the circle's span, and the edge between the two lines. (Summed up, on the grounds that it relies on upon the range of the circle.) In a 360 degrees circle there would be 6.283. 2.4 What is the relationship between the wavelength and frequency of a sine wave?
