Study Notes

Signal Classification

A continuous signal is a signal that can take on any value in a continuous range, and is defined at every point in time.
A discrete signal, on the other hand, is a signal that can only take on specific, distinct values, and is only defined at specific points in time.

Challenges of Continuous Time Signals

Continuous time signals are more difficult to manipulate and analyze mathematically because they have an infinite number of values, making it hard to deal with.
Mathematical operations on continuous time signals require the use of calculus, which can be complex.

Advantages of Discrete Time Signals

Discrete time signals are simpler to work with because they have a countable number of values, making it easier to analyze and manipulate.
Discrete time signals can be analyzed using algebraic methods, which are more straightforward.

Frequency Analysis

The Fourier Transform is a mathematical technique that allows us to represent a signal in terms of its frequency components.
The Fourier Transform decomposes a signal into its constituent frequencies, making it easier to analyze and understand the signal's properties.
