Sampling period

The sampling period is the time difference between two consecutive samples in a Sound. It is the inverse of the sampling frequency. For example: if the sampling frequency is 44100 Hz, the sampling period is 1/44100 = 2.2675736961451248e-05 seconds: the samples are spaced approximately 23 microseconds apart.

How do you determine sampling time?

The sampling frequency should be at least double the maximum frequency. If your measurement is done in the pass-band (2.38 GHz-2.46 GHz), so the maximum frequency is 2.46 GHz which means that the sampling frequency should be at least 2x2. 46 GHz = 4.92 GHz.

What is sampling period in Matlab?

The sample time is the time between successive data samples in your experiment and must be the numerical time interval at which your data is sampled in any units. For example, enter 0.5 if your data was sampled every 0.5 s , and enter 1 if your data was sampled every 1 s .

What is minimum sampling time?

The minimum sampling rate is often called the Nyquist rate. For example, the minimum sampling rate for a telephone speech signal (assumed low-pass filtered at 4 kHz) should be 8 KHz (or 8000 samples per second), while the minimum sampling rate for an audio CD signal with frequencies up to 22 KHz should be 44KHz.

What should my sampling interval be?

To determine an appropriate Sampling interval, consider the Duration of the collection, the speed of your processors, and the amount of software activity. For instance, if the Duration of sampling time is more than 10 minutes, consider increasing the Sampling interval to 50 milliseconds.
