How do you choose a sampling frequency?
Choose your sampling rate to be at least 2x faster than the fastest frequency you want represented in your FFT.
If you're doing like a spectrogram (sliding/windowed FFT over time), then you pick your number of samples based on the lowest frequency you want to show..
How is sampling frequency determined?
The sampling frequency or sampling rate, fs, is the number of samples divided by the interval length over in which occur, thus fs = 1/T, with the unit sample per second, sometimes referred to as hertz, for example e.g. 48 kHz is 48,000 samples per second..
What is sampling in control system?
Sampling process is defined as the conversion of analog signal into the digital signal with the help of a switch (also known as sampler).
A sampler is a continuous ON and OFF switch which directly converts analog signals into digital signals..
What is sampling time in control system?
In engineering, sample time refers to the rate at which a discrete system samples its inputs.
Simulink allows you to model single-rate and multirate discrete systems and hybrid continuous-discrete systems through the appropriate setting of block sample times that control the rate of block execution (calculations)..
What is the sampling frequency of a system?

What is the sampling rate in a digital control system?
One of the critical aspects of digital control systems is the sampling rate, which refers to the frequency at which the continuous-time signal is converted into a discrete-time signal.
The sampling rate must be carefully selected to ensure accurate representation and reconstruction of the analog signal..
What should my sampling frequency be?
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..
- Generally, you want to choose a sampling frequency that is high enough to capture the relevant changes and trends in your process, but low enough to avoid unnecessary noise and waste.
A common rule of thumb is to sample at least 20 times per shift, or every 20 minutes for an 8-hour shift. - One of the critical aspects of digital control systems is the sampling rate, which refers to the frequency at which the continuous-time signal is converted into a discrete-time signal.
The sampling rate must be carefully selected to ensure accurate representation and reconstruction of the analog signal.
