PULSE MODULATION TECHNIQUES INTRODUCTION • Modulation is the process of frequency translation in which any one parameter(Amplitude‚ frequency or phase) of high frequency carrier signal is varied in accordance with instantaneous value of low frequency modulating signal. • Modulation is either analog or digital. INTRODUCTION • Many signals in modern communication systems are digital • Additionally‚ analog signals are transmitted digitally • Digitizing a signal results in reduced distortion

Chapter 2 Chapter Notes FREQUENCY TABLE A grouping of qualitative data into mutually exclusive classes showing the number of observations in each class. You can convert class frequencies to relative class frequencies to show the fraction of the total number of observations in each class. BAR CHART A graph in which the classes are reported on the horizontal axis and the class frequencies on the vertical axis. The class frequencies are proportional to the heights of the bars. The most

of chapter 2 is for you to master several techniques for summarizing and depicting data‚ thereby enabling you to: 1. Recognize the difference between grouped and ungrouped data. 2. Construct a frequency distribution. 3. Construct a histogram‚ a frequency polygon‚ an ogive‚ a pie chart‚ a stem and leaf plot‚ a Pareto chart‚ and a scatter plot. CHAPTER TEACHING STRATEGY Chapter 1 brought to the attention of students the wide variety and amount of

Therefore‚ it is an interval scale variable. 4. The number of people eating at a local café between noon and 2:00 p.m. is an example of a discrete variable. TRUE Chapter25. When establishing the classes for a frequency table it is generally agreed that the more classes you use the better your frequency table will be. FALSE We try to follow the 2k rule. Having too many classes is not good.6. The cumulative distribution function is never decreasing. TRUE It is always increasing and becomes flat at the end
