What is the formula for exponential smoothing method? This method is used for forecasting the time series when the data has both linear trend and…
What is the magnitude response of Butterworth filter? Note that the Butterworth is a good compromise, realizing both a reasonable roll-off and phase response. The…
What is delta modulation and how does it work? Delta modulation process compares the present sample value to the previous sample value. Based upon the…
What does DC level mean? DC level in signal processing refers to the average or the mean value of a signal. So a zero-mean signal…
What is the advantage of Gaussian filter? A Gaussian filter has the advantage that its Fourier transform is also a Gaussian distribution centered around the…
What is a mel filter bank? Mel filter banks do exactly that by giving a better resolution at low frequencies and less at high. Triangular…

What is bin and frequency? frequency bins are intervals between samples in frequency domain. For example, if your sample rate is 100 Hz and your…
What are linear-phase filters? Linear phase is a property of a filter where the phase response of the filter is a linear function of frequency.…
What is the difference between GMSK and GFSK? With GMSK, the frequency modulation index is 0.5. With GFSK, the frequency modulation index is larger than…
