issingle
Determine if digital filter coefficients are single precision
Syntax
Description
Examples
Single- and Double-Precision Filters
Use designfilt
to design a 6th-order highpass IIR filter. Specify a normalized passband frequency of rad/sample. Convert it to a single-precision filter. Identify the precision in each case.
fd = designfilt('highpassiir','FilterOrder',6,'PassbandFrequency',0.6); isd = issingle(fd)
isd = logical
0
fs = single(fd); iss = issingle(fs)
iss = logical
1
Input Arguments
d
— Digital filter
digitalFilter
object
Digital filter, specified as a digitalFilter
object. Use designfilt
to generate d
based
on frequency-response specifications. If you want a single-precision
filter, apply single
to the
output of designfilt
.
Example: d = designfilt('lowpassiir','FilterOrder',3,'HalfPowerFrequency',0.5)
specifies
a third-order Butterworth filter with normalized
3-dB frequency 0.5π rad/sample.
Output Arguments
flag
— Type identification
logical scalar
Type identification, returned as a logical scalar.
