Introduction: It is a digital modulation technique which shifts the frequency of the carrier with respect to binary data signal. What is FSK? For the first group, halfway between 0 and 16 is 8 – this is the midpoint. Dependent on ability, this lesson could be split into two lessons. The second half of the lesson could present a good opportunity to teach students how to calculate the mean value in a calculator using the statistics mode. "(a) Draw a frequency polygon to show this information on the diagram above. The midpoint of any group is the number that lies halfway between the two boundaries. The louder signal causes greater frequency change in modulated carrier as indicated by increased bunching and spreading of the waves as compared with relatively weaker signal.
