In the ‘Dark’ setting, the entire frequency response is tilted so that 20kHz is down -1.5dB, while 20Hz is up +1.5dB. In ‘Bright’, the tilt is reversed (+1.5dB at 20kHz and -1.5dB at 20Hz). This gentle filter maintains the proper phase response between the drivers while ...
Similar to upsampling in data science, upsampling for DSP artificially creates more samples in a frequency domain from an input signal (specifically a discrete time signal) by interpolating higher sampling rates. These new samples are generated by inserting zeros into the original signal and using a...

sampling frequency is often done by reducing the sampling rate by some integer factor, keeping only one of everynthsample. This is done by using a lowpass filter, otherwise known as an anti-aliasing filter, to reduce the high frequency/noise components of a discrete-time signal by the ...
In the next period, you choose another thing. You continually “cycle” through different inventory items until you get back to the beginning and start anew.Cycle counts also often skip full physical counts in favor of “sampling.” What is sampling? It’s basically counting a small number ...
The concepts are the same in terms of the sampling frequency and the number of bins, however the Goertzel only calculates the value for one of the bins. Conclusion The Fourier Transform is a very interesting concept, and has extensive applications in engineering. Whilst we haven’t delved into...

The Spurious-Free Dynamic Range (SFDR) of a receiver is a ratio of the amplitude of the fundamental carrier signal to the amplitude of the strongest spurious signal in the frequency range of interest. SFDR is usually measured in dBc (i.e. with respect to the carrier signal amplitude). SF...
Fs = sampling_frequency; Fn = Fs/2; L = numel(original_signal); NFFT = 2^nextpow2(L); FToriginal = fft(original_signal).*hann(L), NFFT)/L; FTfiltered = fft(filtered_signal).*hann(L), NFFT)/L; Fv = linspace(0, 1, NFFT/2+1)*F...
There is no way to fix it with software. It must be prevented either by always sampling faster than the Nyquist frequency of all input signals or by filtering the signals before and within the ADC. For more details see Aliasing and the Danger of Under-sampling below SAR ADCs are a solid...
