Phase generator |
摘要 |
A digital down converter with a programmable mixing down frequency and a programmable extraction bandwidth uses a ROM based sin/cos generator plus a programmable high decimation filter followed by a gain compensating scaling multiplier and a fixed FIR filter. Output format options are also programmable, and programming commands are serially loaded into registers. Various components may be isolated for efficient testing and also subsystem operation.
