3. (15 pts) For the following calibration techniques: (a) Standard addition, (b) External calibration, and (c) Internal calibration: Draw a picture of what each graph would look like, describe each technique, and give a reason why each might be used for quantification (an advantage of each). *just wants a general example plot, not data is provided for this problem.*

If every RF power measurement has a calibration uncertainty of 0.15 dB

If every RF power measurement has a calibration uncertainty of 0.15 dB, discuss the relative accuracy of RF path calibration by separately calibrating individual components versus doing a single end-to-end calibration

Kindly summarize this Literature Review Section 3.2 Efficient Techniques and Performance Measurement Recently, developed techniques compare the efficiency of similar service organizations by explicitly considering their use of multiple inputs to produce multiple outputs. These new efficiency techniques are often divided into two categories. One broad category consists of the linear programming procedures used in this paper (DEA). The second category is a set of regression-based techniques that derive inefficiency estimates from two-part error terms, and has been called the...
