Relation between baud rate and sampling rate and regarding simulation in Simulink

1. Is baud rate and sampling rate same?
2. How is bandwidth related to sampling rate?
3. Is sampling rate the same as sampling frequency?

Is baud rate and sampling rate same?

The baud rate is how fast I can open and close the shutter. The sample rate is how often you look at my flashing light. For information to flow, you need to look (sample) faster than I'm flashing.

How is bandwidth related to sampling rate?

Sampling rate determines the sound frequency range (corresponding to pitch) which can be represented in the digital waveform. The range of frequencies represented in a waveform is often called its bandwidth.

Is sampling rate the same as sampling frequency?

Sampling rate (sometimes called sampling frequency or F_s) is the number of data points acquired per second. A sampling rate of 2000 samples/second means that 2000 discrete data points are acquired every second.
