SIGNAL PROCESSING |
| 摘要 |
A method of processing an amplitude-modulated analogue signal at a carrier frequency Fc comprises: digitising the analogue signal to produce an input bit stream that represents the amplitude of the analogue signal; generating an in-phase reference bit stream that is synchronous to the carrier frequency Fc and represents an in-phase digital reference signal substantially in the form of a sine and/or cosine wave; and multiplying the input bit stream with the in-phase reference bit stream to produce an output bit stream representing the amplitude modulation of the analogue signal. |
