In this tutorial, we are showing what is Sampling? and How to sampled an analogue signal using MATLAB software.
Step 1: What Is Sampling?
Conversion of Analogue Signal (xt) to Digital Signal (xn) is known as Sampling.
A continuous time signal can be represented by its samples and can be recovered back when sampling Freq (Fs) is greater than or equals to twice the message signal (Nyquist Rate).
Step 2: Display Commands to Enter Frequency
Enter Frequency of Message signal and Sampling Frequency.
Step 3: Specify Time Range of Signal
Step 4: Write Formula
As:
x=sin(2*3.14*f*t)
Step 5: Write Sampling Formula
As:
y=sin(2*3.14*f*ts/fs)
Step 6: Enter Frequency
Step 7: Result
Upper Signal: Orignal
Lower Signal: Sampled
Step 8: Complete Video Tutorial
