# orderwaveform

Extract time-domain order waveforms from vibration signal

## Syntax

## Description

returns
the time-domain waveforms corresponding to a specified set of orders
present in an input signal, `xrec`

= orderwaveform(`x`

,`fs`

,`rpm`

,`orderList`

)`x`

. `x`

is
measured at a set `rpm`

of rotational speeds expressed
in revolutions per minute. `fs`

is the measurement
sample rate in Hz. The vector `orderList`

specifies
the desired orders, whose waveforms are returned in the corresponding
columns of `xrec`

. The function uses the Vold-Kalman
filter for the computation.
