Electrical Safety in Operating Rooms: Installation Requirements

1. Purpose and Scope

The purpose of this investigation is to determine the specific requirements for electrical equipment in operating rooms and intervention halls, and the conditions for installing the receivers in receiving them. The object of this is to meet the requirements of applicable European Directives under the provisions in Article 6 of the Regulation for Low Voltage Electro.

In addition to the local general requirements for sanitary purposes identified in the ITC-BT-28, the detailed requirements

Telecommunications Signals and Transmission Media

Mathematical Concepts

A signal is only the manifestation of a physical quantity. In the case of signals used in telecommunications, this signal has a characteristic: it can spread through various means and channels. This suggests the idea of mathematically representing the signal as a function variable over time.

  • Frequency: The frequency reports on the number of sections of the horizontal axis function per unit time, measured in hertz (Hz).
  • Period: The period reports the time needed for a repetition
