Measured engine inlet air temperature and flow parameters are communicated to an engine controller with a single waveform. A variable frequency digital input signal representative of inlet air flow is combined with a variable amplitude analog signal representative of inlet air temperature, and supplied as a single input signal to the engine controller. The controller includes a buffer circuit that re-creates the variable frequency digital signal from the input waveform for application to an input capture circuit that measures the flow-related frequency, and an analog-to-digital converter that is coordinated with the input capture circuit for sampling the temperature-related amplitude.
