Dido, The mathematician. She was an ancient queen of Carthage. If she never existed, our world would have been totally different, for example, the progenitors of the founders of Rome would have been different. Maybe Rome would even not have been founded.
The signal v(t) from m is a binary waveform. It is either 0.5 V or -0.5 V. The sign change has a 50-50 chance of occurrence within the interval of 1 μs. In other words, v(t) has an equal chance for positive or negative values within this interval.
What is the average and effective values of v(t) over a period of 5 secs?
Figure 2.13 shows two sinusoids (red, blue) representing the periodic signals of m.
(a) Which signal is a cosine function and which is a sine function?. Write the general form of the signals
(b) Express the cosine signal as a sine signal and the sine signal as a cosine signal.
