Question:

The data in Table 11-13 are input samples taken by an A/D converter. Notice that if the input data were plotted, it would represent a simple step function like the rising edge of a digital signal. Calculate the simple average of the four most recent data points, starting with OUT[4] and proceeding through OUT[10]. Plot the values for IN and OUT against the sample number n as shown in Figure 11-41.

Sample calculations:

(IN[n OUT[n] OUT[4] (IN[1] OUT[5] = (IN[2] = - - 3] + IN[n  2] + IN[n + IN[2] + IN[3] + IN[3] + IN[4] 1] +

(Notice that this calculation is equivalent to multiplying each sample by 1/4 and summing.)
