Abstract
Signal: characterization, enhancement, noise suppression
examples: image restoration, speech enhancement
System: characterization, synthesis
examples: chemical processing plants
Analysis tool: Fourier analysis, Fourier series, Fourier transform
Signal type:
continuous: voltage in a circuit, temperature,…
discrete: closing stock market average, …
• Quantization of continuous signals into discrete signals.
• DSP ( digital signal process) is possible due to advance in
computer and digital signal processing power.
– Audio (CD, MP3) , Video (VCD, DVD, DVB) , …
• Continuous and discrete formulations are presented is
parallel in this book. They are similar but not identical.
