■授業内容と方法 |
In this lecture, the discrete-time system and the frequency domain representation and its impulse response will be studied. Stability, causality,linear-shift invariance will be explained. Then, the Z-transform and the Digital filters, both FIR and IIR, will be studied and designed.The discrete Fourier transform (DFT) and its fast implementation algorithms (FFT) are another purpose of signal processing study in order to get knowledge of the spectral specification of a signal.There are many areas for DSP applications, to name some, digital image processing, medical image, remote sensing, seismology, speech processing, speech recognition, noise and echo canceling, image and speech coding for image phone and teleconference system, and many many other applications in fields of communications and control Engineering can be found to utilize DSP for a faster, reliable and cheaper implementation.
