As A/D converters move closer to the antenna of a digital receiver, the need to handle broadband signals efficiently in the digital domain is increasing. Efficient Polyphase/FFT Filter Banks (aka Channelizers) are a natural extension to traditional Polyphase Decimators that can handle broadband multi-channel signals efficiently.

This talk will cover:

• How channelizers are derived and implemented
• Considerations in designing a prototype filter
• Oversampled channelizers
• Showcase simulations demonstrating using channelizers with broadband signals
