Abstract
A transmitter for use in a process control setting includes a sensor adapted to couple to a process and provide a sensor output related to a parameter of the process. A modulator coupled to the sensor output responsively provides a digital bit stream output representative of the sensor output. A filter provides a current decimation output. A comparator compares a previous decimation output with the current decimation output. Circuitry is provided for transmitting an output related to the parameter based upon the current decimation.
