timeDomainSignal2RiseTime

Measure rise time of time domain signal

Syntax

Tr = timeDomainSignal2RiseTime(Tin,Vin,RefLevel)

Description

Tr = timeDomainSignal2RiseTime(Tin,Vin,RefLevel) returns the rise time of the time-domain input signal represented by [Tin, Vin].

Examples

Rise Time of Time-Domain Signal

Determine the rise time of a time-domain signal.

load tin.mat;
load xin.mat;
plot(t,x)

RefLevel = [20 80];
Tr = timeDomainSignal2RiseTime(t,x,RefLevel)

Tr = 5×1
10-8 ×

Input Arguments

Tin — Sample time points in signal

vector

Sample time points in the signal of interest, specified as a vector of the same length as Vin.

Data Types: double

Vin — Signal values at sample time points

vector

Signal values at the sample time points defined in Tin, specified as a vector of the same length as Tin.

Data Types: double

RefLevel — Reference levels as percentage of waveform amplitude

2-element positive row vector

Reference levels to calculate rise time as a percentage of waveform amplitude, specified as a 2-element row vector of positive values. The reference levels must be in increasing order.

Data Types: double

Output Arguments

Tr — Rise time of input signal

vector

Rise time of the input signal, returned as a vector of the same length as the number of rising edges in the signal.
