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.
