Introduction

The increasing speeds and dynamic ranges of modern communication and control systems make for complex filter requirements that have been, until now, a challenge to satisfy. Signal converters with high sampling rates can alleviate the need for selective filters, but even so, some sort of band limiting is still required. Some wireless systems face yet another problem. Even though the use of oversampling converters has significantly simplified filtering, unexpected signals from neighboring ...
