2. Need for Transform
• Transforms make some types of calculations
much simpler and more convenient.
• Transforms are tools to make analysis easier.
• Laplace transform, for example, makes solving
differential equations easier.
• Possible to do all computation and analysis of
a signal in either the time domain or the
frequency domain.
