1 Scope

This section provides terms and definitions oscillation, signals and related devices. This section applies to telecommunications technology.

2 Terms and definitions

2.1 Frequency 702-01-01 For transmitting information electromagnetic oscillations or electromagnetic waves of frequency range. 702-01-02 In the period between two successive predetermined frequency limits frequency. Note. The band is stipulated by its two values \u200b\u200b(for example, the upper limit frequency and lower limit frequency) spectrum position to represent. 702-01-03 Defining difference between the two frequency bands between. Note 1. The frequency bandwidth is usually with a qualifier, for example. baseband bandwidth, necessary bandwidth, the bandwidth of an amplifier or other device bandwidth. Note 2. The frequency bandwidth with a single value to define, and independent of their position in the spectrum. 702-01-04 In the device or transmission channel, given the frequency characteristics of the reference value does not deviate by more than a predetermined value or ratio of the frequency bandwidth when. Note. Given the frequency characteristics such as amplitude/frequency characteristic and phase/frequency characteristic or the delay/frequency characteristics. 702-01-05 A type of signal frequency bandwidth, over the upper limit and the lower frequency, any line signal spectrum or power spectral density than that under consideration Specific reference level at least lower X dB. 702-01-06 On the transmission system-specific input and output points, by one or several signals multiplexed signal occupied band. Note 1. In radio communication, the baseband modulation signal generated by the transmitter means of occupied band. Note 2. When using multi-level modulation, the baseband is usually applied to the first stage of the modulation signal occupied band, not the middle of the modulated signal occupied frequency band. 702-01-07 In physical systems, when the excitation source is removed, the frequency of free oscillations can be any existence.
