  • Digital barometric altimeter
    Patent number: 4507962
    Abstract: A digital barometric altimeter has an electrical pressure transducer juxtaposed with a pitostatic port, and has a processor located remotely from the port, interconnected with the transducer by an analog-to-digital converter. The processor filters the pressure-responsive data, linearizes it, and converts it to altitude-representative data, using a "jump-and-converge" procedure. The altitude-representative output may be supplied to a display or other utilization device.
