7. PARAMETER DEFINITIONS
Signal to Noise Ratio (SNR)
The ratio of the RMS value of the output signal, where Pout is equivalent to the specified output power at
THD+N<1%, to the RMS value of the noise floor with no input signal applied and measured over the spec-
ified bandwidth, typically 20 Hz to 20 kHz. Expressed in decibels.
Dynamic Range (DYR)
The ratio of the RMS value of the output signal produced when Pout is equivalent to the specified output
power at THD+N<1% to the RMS sum of all other spectral components over the specified bandwidth, typi-
cally 20 Hz to 20 kHz. Dynamic Range is a signal-to-noise ratio measurement made with a -60 dBi input
signal where dBi is referenced to the input signal amplitude resulting in the specified output power at
THD+N<1%. This technique ensures that the distortion components are below the noise level and do not
effect the measurement. Expressed in decibels.
Total Harmonic Distortion + Noise (THD+N)
The ratio of the RMS value of the signal to the RMS sum of all other spectral components over the specified
band width (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels.
