A binary signal v(t) is either at 0.5 or −0.5 V. It can change its sign at 1-ms intervals. The sign change is not known a priori, but it has an equal chance for positive or negative values. Therefore, if measured for a long time, it spends an equal amount of time at the 0.5-V and −0.5-V levels. Determine its average and effective values over a period of 10 s.
