In aircraft systems and engineering, “frequency” typically refers to the measurement of how often a periodic event occurs within a specified time interval. Frequency is a fundamental parameter used in various aspects of aircraft systems, including avionics, communication systems, and navigation. Here’s the definition and SI unit for frequency in aircraft systems:
Formula: Frequency is often measured directly using various frequency measurement devices or instruments such as frequency counters, oscillators, or signal generators.For example, the formula for calculating frequency based on the number of cycles (N) within a given time period (T) is:
- Frequency (f) is measured in hertz (Hz).
- Number of Cycles (N) represents the count of occurrences.
- Time Period (T) is the duration over which the count is made and is measured in seconds (s).
