2023年1月14日 · In dB quantity this would be $20log_{10}(10) = 20 $ dB. The asymptote will stay flat at 20 dB, until we reach $\omega = 0.2$ , at which point the magnitude will drop at -20 dB …

In the analog realm, power is V^2/R, where V and R are voltage and impedence across that voltage respectively, so we have dB = 10*log((V1^2/R1) / (V2^2/R2)) = 20*log(V1/V2) + …

2023年7月24日 · The cinema standard is a 500-2000 Hz band-limited pink noise signal with digital RMS amplitude of -20 dB full scale will produce 85 dBC SPL slow response at the listening …

You don't need to convert the voltages to dB, just calculate the required gain (as a factor) and then convert this to dB if necessary, i.e. G = Vout / Vin # required gain (factor) G_dB = 20 * …

If the slope is -20 dB/dec then the second order should have -40 dB/dec. For example, An n= 4th order is 24dB/octave slope. But, I saw this example below and pretty confuse about determine …

2022年8月5日 · From the looks of it, it appears to be influenced a lot of what a medical professional would consider a problem. For example according to ISO 226, the threshold of …

2024年7月5日 · If one of the noise types is more dominant (in a given frequency or time range), then that is the slope you will see---it is often common to see a PSD (welch) where it drops …

2021年9月3日 · How is pass band ripple related in dB scale? The magnitude response of a filter is typically plotted on a dB scale, so it is natural to specify the ripple in dB as well, but you can …

2023年2月2日 · If the noise floor (as a spectral density) at the IF port was the same in the desired band and alias band, then the noise floor at the RF output of the mixer would be degraded by …

2020年8月18日 · assuming it's a low-pass filter and assuming that the filter order equals the number of poles and there are no zeros in the s-domain transfer function, then the rolloff at the …
