How do you get rid of high-frequency noise?
A low-pass filter is a common techqnique for removing high-frequency noise in a signal.
What is resampling in signal processing?
resample Function
One resampling application is the conversion of digitized audio signals from one sample rate to another, such as from 48 kHz (the digital audio tape standard) to 44.1 kHz (the compact disc standard).
Is resampling the same as interpolation?
Resampling is used to either increase the sample rate (make the image larger) or decrease it (make the image smaller). Interpolation is the process of calculating values between sample points. So, if you resample an image you can use interpolation to do it.
