Active Devices and Circuit Models,nged, can have a power transfer function greater than unity. An active circuit on the other hand contains elements which have the possibility of power amplification though in some configurations such amplification or gain may not occur.

Positive Feedback and Frequency Response, Providing the sign of the open-loop gain .(s) is positive, the feedback is negative and the closed-loop gain is reduced. Conversely, if .(.) is negative, perhaps because it is a function of frequency, then |.(.)| >|.(.)|. Should the loop gain equal −1 the overall gain becomes infinite and the amplifier acts as an oscillator.

Radiation Protection and Exposure in Nuclear Cardiology, medicine facilities. The dose reference level (DRL) for nuclear cardiology examinations has regional characteristics and must be changeable as equipment instrumentation and image processing programs advance. Radiological safety should always be guided by the pillars of justification, optimization, and dose limits.
