chapter 2 는 signal에 대한 내용

this posting develops mathematical tools that are used to describe signals and noise from a deterministic waveform point of view. (the random waveform approach is given in chapter 6) the waveforms will be represented by derect mathematical expressions or by the use of orthogonal series representations such as the Fourier series.

properties of these waveforms, such as;

• DC value
• root-mean-square (RMS) value
• normalized power
• magnitude spectrum
• phase spectrum
• power spectral density
• bandwidth

 

• in addition, effects of linear filtering

will be established.
