What is the ideal sampling rate for an analog signal?
To get an accurate picture of the waveform you will need a sampling rate of 10 to 20 times the highest frequency.
What is the minimum sampling rate required in order to recovered the information signal?
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 is sampling frequency in DSP?
Definition: Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.
What is sampling of analog signal?
Sampling is the process of taking an analog signal and converting it to discrete numbers. The sampling frequency (or sampling rate) is how many times per second the signal will be sampled. This is important because it restricts the highest frequency that can be present in a signal.
