Final answer:
Delay on a track can be shown using electronic detection systems for precise timing or through theoretical calculations based on physical properties. Additionally, it can be expressed in terms of sample rate and the number of samples in audio processing scenarios.
Step-by-step explanation:
There are two common ways to show the number of samples of delay incurred on a track. The first method involves using electronic detection systems that can automatically start and stop the timing based on the detection of an event, such as a signal change.
This method is similar to the use of electronic detection in measuring elapsed time for races to avoid inaccuracies due to human reaction time. The second method could be theoretical, where calculations are based on known physical properties such as the speed of light or sound, and the distances involved.
In situations where the delay is due to electronic signal processing, the delay can also be referred to in terms of sample rate. For example, with a sample rate of 44.1 kHz, each sample represents approximately 22.68 microseconds of time. By knowing the sample rate and the number of samples of delay, one can calculate the delay time.
There are two ways to show the number of samples of delay incurred on a track:
Absolute Time: This method measures the exact time it takes for an event to occur. For example, using a stopwatch to time the delay between the starting signal and a car crossing the finish line.
Relative Time: This method compares the delay between two events. For instance, measuring the time interval between two flashes of light produced by flash lamps on a moving train.
