DIGITAL FREQUENCY DEMODULATOR WITH LOW POWER CONSUMPTION AND RELATED SYSTEM AND METHOD |
摘要 |
An apparatus includes a frequency counter configured to receive an input signal containing pulses and to output a count value identifying a number of pulses in the input signal during a specified time period. The specified time period encompasses multiple cycles of the input signal. The apparatus also includes a comparator configured to receive the count value, compare the count value to a second value, and provide an output signal based on the comparison. The apparatus further includes a data latch configured to latch the output signal, where the latched value of the output signal represents a demodulated data value. The comparator could be configured to compare the count value to a fixed value associated with a desired frequency of the input signal. The comparator could also be configured to compare the count value in one specified time period to a stored count value from another specified time period. |
