) direct measurement and (2) indirect measurement. Direct measurement involves counting the number of cycles of the signal over a given time period and calculating the frequency. Indirect measurement involves measuring the period of the signal and calculating the frequency from the reciprocal of the period. Both methods require a high-precision timer and counter to accurately measure the frequency. The equal precision frequency meter uses a combination of these methods to achieve high accuracy and precision in frequency measurement. It is particularly useful in applications where a stable and accurate frequency source is required, such as in telecommunications, audio and video production, and scientific research
