Performs a full Signal in Noise and Distortion (SINAD) analysis, including measuring the fundamental frequency tone and returning the fundamental frequency and SINAD level in dB.
Source of the signal and spectrum to export.
|none||Uses the fastest computation.|
|input signal||Exports the input signal only.|
|detected signal||Exports a single tone.|
|residual signal||Exports a signal minus the tone.|
Center frequency to use in the frequency-domain search for the fundamental tone frequency.
Frequency width, as a percentage of the sampling rate, for the frequency-domain search for the fundamental tone frequency.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Spectrum of the exported signal.
Start frequency, in Hz, of the spectrum.
Frequency resolution, in Hz, of the spectrum.
Waveform of the exported signal.
Detected fundamental frequency resulting from searching the frequency domain.
Use the center frequency and frequency width to set the frequency domain search range. All harmonics are measured at integer multiples of this fundamental frequency.
Measured Signal in Noise and Distortion (SINAD) expressed in dB.
This output is the ratio of the RMS energy of the input signal to the RMS energy of the input signal less the energy in the fundamental. To compute the measured total harmonic distortion plus noise in dB, negate the SINAD in dB
Measured total harmonic distortion (THD) plus noise.
This output is the ratio of the RMS energy of the input signal less the energy in the fundamental to the RMS energy of the input signal. To compute this output as a percentage, multiply the value by 100.
Error information. The node produces this output according to standard error behavior.
