Digital Signal Processing — purpose?
Converts analog signals into digital form for analysis and manipulation.
Sampling — key requirement?
Must be at least twice the highest frequency (Nyquist rate).
Fourier Transform — role?
Converts signals from time domain to frequency domain.
Digital Signal — definition?
Sequence of discrete values representing information.
Sampling — process?
Converting continuous signals into discrete by measurements.
Nyquist Rate — requirement?
Sampling at least twice the highest frequency.
Quantization — role?
Mapping continuous amplitudes into discrete levels.
FFT — purpose?
Efficient computation of the Discrete Fourier Transform.
Filtering — function?
Removing or attenuating specific frequency components.
Time vs Frequency — analysis?
Different domains for analyzing signals.
