Webfor frequency measurements is usually at a frequency of 1 MHz or higher, with 5 or 10 MHz being common. Frequency signals are usually sine waves, but can also be pulses or square waves. If the frequency signal is an oscillating sine wave, it might look like the one shown in Fig. 17.1. This signal produces one cycle (360 ∞ or 2 π WebConversely, the period is the reciprocal of the frequency, T = 1/ f. Since the period is a time interval expressed in seconds (s), it is easy to see the close relationship between time …
