• Biological signals – A set of DNA / gene-based sequences
• Video signals – Alteration of intensity in an image

A system is a compilation of one or more processes, devices, or computer-executed algorithms that functions on an input signal X to create an output signal Y.

##### What are the functions in Signals and Systems?
• Quantization: It is defined as separating into partitions. Quantization is executed on the dependent variable. Quantization is contradictory to sampling.
• Sampling: Sampling is getting a specimen. Get a specimen of a digital signal above the x-axis. Sampling is executed on an independent variable. Sampling techniques are of three types:
• Flat Top sampling
• Natural sampling
• Impulse sampling
• Scaling: It is simply meant as the accumulation of a stable signal of amplitude or time.
• Integration: Signal integration signifies the signal outline to acquire a modified signal below a certain time domain.
• Shifting: Shifting is simply meant as signal progress, whether in a domain of amplitude or a domain of period. Consequently, shifting can be classified into two, they are: Shifting of amplitude or Shifting of the period.
• Differentiation: Signal Differentiation signifies slope depiction of that signal concerning time
• Reversal: Whenever a time of the signal is accumulated by -1, it is identified as Signal reversal time.
