Question: What is the main advantage of using an FIR filter over an IIR filter?

Options:

1. FIR filters are easier to implement
2. FIR filters can have a linear phase response
3. FIR filters require less computational power
4. FIR filters are always more efficient

Correct Answer: FIR filters can have a linear phase response

Solution:

FIR filters can be designed to have a linear phase response, which preserves the wave shape of filtered signals.
