ABSTRACT:
One embodiment of the present invention enables a low performance and low cost microprocessor (or microcontroller) to perform binary demodulation of analog communication signals. Within the present embodiment, three techniques may be utilized to enable this functionality. For example, an analog-to-digital converter sampling rate technique is utilized with an incoming modulated analog communication signal. This sampling rate technique is able to eliminate the need for any reference sine and/or cosine waves during the demodulation process. Next, utilizing sample values produced by the sampling rate technique, a continuous-time sum of products calculation is performed by a central processing unit (CPU) of the microprocessor or microcontroller. The results of the continuous-time calculation then enables the present embodiment to demodulate the binary modulated analog signal. An optional digital low pass filter may also be implemented in order to eliminate situations where a false detection of frequency may happen.
