peak amplitude of a waveform divided by the
RMS value. The purpose of the crest factor
calculation is to give an analyst a quick idea
of how much impacting is occurring in
a waveform.
The screen displays: V1, V2,V3.
THFF (Telephone Harmonic Form Factor)
The harmonic interference may cause noise in
the system and influence the quality of
communication; our hearing and the telephone
cannot respond well to the 50Hz current and
voltage but can respond better to about 1KHz
current and voltage. In Europe, CCITT detects
harmonic interference to telecom with Pn, then
figures it with THFF. It is 0 with no harmonic.
The Screen displays: V1,V2,V3.
