Apr 22, 2013 · I asked myself how to compute dBFS (dB full scale) from a value of sample between 1 and -1? and in general?

Apr 13, 2023 · It is probably very well known that dBFS cannot be directly converted to dB SPL without knowing other information such as the technical specifications of the microphone. The …

Dec 14, 2014 · If your hardware driver takes the usual floating-point convention of the absolute extreme sample values being from −1 to +1, then you can say that your dB power values are …

Jan 7, 2022 · The resolution in dB/LSB can be thought of as a multiplicator. With 1dB/LSB (Least Significant Bit), the dBFS-Value can be directly obtainend by reading the register. So, an 8Bit …

0 I'm trying to figure out how to calculate the dBFS for a complex input. I have an AD9361 part which has a 16-bit A/D and I believe outputs I and Q samples. Now I know you can calculate …

Jan 9, 2023 · More details: Quantization noise is well approximated as a uniform white noise, from which we derive the equation for the total power due to quantization noise relative to the power …

Aug 22, 2022 · As per my current understanding, the ADC datasheets for modern high speed ADCs give the noise level measurements in terms of Noise Spectral Density (NSD) in unit of …

Spectrum scaling is tricky for a number of reasons, including sometimes-ambiguous definitions and inconsistent scaling factors that vary among FFT implementations. You should be able to …

Jul 11, 2016 · Definitely you will have to calibrate your system. You need to know what is the relationship between dBFS (Decibel Full-Scale) and dB scale you want to measure. In case of …

Apr 28, 2015 · I'm trying to get the spectrum of my signal in dBFS units. I'm not sure what is the refernce that I should devide by. I computed the power spectrum as follows: 1) FFT …
