IC Phase-locked Loops (PLL) Specification Guide
IEEE GlobalSpec

IC phase locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator. An IC phase-locked loop generally consists of a phase detector, a loop filter, voltage...

1B-1944 - AIEE Report on Guiding Principles for the Specification of Service Conditions in Electrical Standards
1944 Edition, January 12, 1944 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In the various standards there will be found a number of different situations regarding Usual Service Conditions. The following three are typical.1. The group where the maximum ambient temperature is specified. The Standards for Bushings, Fuses, Lightning Arresters, Protector Tubes and...
