DSP LEC 2

often referred to simply as fundamental, is defined as the lowest frequency of a periodic waveform

The reciprocal of fundamental frequency is called ____________________

The _________________ of a signal is the Greatest Common Divisor (GCD) of all the frequency components contained in a signal.

The _________________ is the least common multiple (LCM) of all individual period of the components.

ω often used to represent ________________________.

is a sequence of numbers (samples) in which each number is represented by a finite number of digits (finite precision)

process of converting a discrete time continuous amplitude signal into digital signal by expressing each sample value as a finite number of digits. It is simply an approximation process.

eliminating the excess digits by discarding them.

eliminating the excess digits by by rounding the resulting number

error introduced in representing the continuous-valued signal by a finite set of discrete-value level.
