ABSTRACT:
A solid-state barometric altimeter-encoder. The atmospheric pressure is cared to a reference vacuum on a hybrid IC pressure transducer which generates a proportional signal. This analog signal is then converted into digital data, corrected for atmospheric to altitude non-linearity by use of a ROM look-up table, displayed as a digital readout and also converted to Grey code format for transponder MC (altitude) transmission.
