Definition: ratio between the time period (t1), in which the output voltage is above a specified level, and the time period (t2), in which the output voltage is below the specified level

Figure 17 – Characteristics of an output waveform

Note 1 to entry: The symmetry is expressed in percent of the duration of the full signal period.

Note 2 to entry: The specified level may be the arithmetic mean between levels VOL and VOH, or 50 % of the peak-to-peak amplitude. The ratio is expressed as:

100 t 1 t 1 + t 2 : 100 t 2 t 1 + t 2 MathType@MTEF@5@5@+=feaagCart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaamaalaaabaGaaGymaiaaicdacaaIWaGaaGjcVlaayIW7caaMi8UaaGjcVlaadshadaWgaaWcbaGaaGymaaqabaaakeaacaWG0bWaaSbaaSqaaiaaigdaaeqaaOGaey4kaSIaamiDamaaBaaaleaacaaIYaaabeaaaaGccaGG6aWaaSaaaeaacaaIXaGaaGimaiaaicdacaaMi8UaaGjcVlaayIW7caaMi8UaaGjcVlaadshadaWgaaWcbaGaaGOmaaqabaaakeaacaWG0bWaaSbaaSqaaiaaigdaaeqaaOGaey4kaSIaamiDamaaBaaaleaacaaIYaaabeaaaaaaaa@55DA@
