摘要： A system for acquiring environmental information measurements. The 5 system (100) utilize a sensor, (205) a front-end circuit, (310) a loop filter (315), a switch controller (206), and a reduced-order loop control circuit to provide reliable data measurements while providing robust system behavior. The system further includes a sensor simulator (330) for simulating the operation of the sensor (205) and testing the operation of the front-end circuit (310) and the loop filter (315).

摘要： A method and apparatus for generating correction signals for use in forming low distortion analog signals. A digital representation of a desired analog waveform is encoded into a digital data signal which is outputted to memory. A digital correction signal is encoded, having an opposite phase and increased amplitude from the signal distortion which it is determined will occur when the digital data signal is repetitively read out of memory and decoded. This digital correction signal is outputted to memory. The digital data and correction signals are repetitively and synchronously read out of memory into a decoder. The decoder converts both digital signals into analog signals, so that the analog correction signal may superpose on the distortion in the analog data signal, resulting in a low distortion analog signal.
