摘要： A temperature regulated feed forward amplifier for use in broad bandwidth cable communications applications, includes an IC amplifier, a fixed voltage power supply for the IC amplifier, temperature sensing circuitry for detecting temperature variations from a preselected reference temperature and regulating the voltage from the fixed voltage power supply to maintain the gain and resultant phase of the amplifier relatively uniform over the bandwidth and over a range of temperatures.

摘要： A method of predicting performance characteristics of an aircraft including modeling thrust-minus-drag of an aircraft with at least one mathematical model using aircraft specific data and input parameters which define the performance characteristics. Coefficients of the at least one mathematical model are learned over at least one flight. The performance characteristics are predicted as a function of the learned coefficients representative of a combined and non-independent thrust-minus-drag relationship.
