- And just about every TV set uses one!

- In this case it is used as a high performance bandpass filter and works at IF
- frequencies -- 30..40MHz or maybe much higher.

- An analogy is a tranversal filter which shows similar charactersitics. The
- excellent group delay characteristic provided one of the big advances in TV
- performance in recent years.
