| An Efficient Technique for Design of Wideband Digital Receivers |
|
| () |
| Abstract: |
| The design technique for wideband digital receivers is introduced.The poly-phase filtering and equivalent circuit relations under certain condition are employed to put decimation process ahead of those of mixing and filtering,so as to receive wideband signals efficiently.Computer simulation results prove the technique is feasible. |
| Key words: wideband digital receiver,DDC,poly-phase filtering,decimation |
