filter design -凯发k8网页登录

digital filters are central to almost every signal processing system. filters eliminate unwanted artifacts from signals to enhance their quality and prepare them for further processing. digital filters are used in a variety of signal processing tasks including outlier and noise removal, waveform shaping, signal smoothing, and signal recovery.

matlab^® and dsp system toolbox provide extensive resources for filter design, analysis, and implementation. you can smooth a signal, remove outliers, or use interactive tools such as tool to design and analyze various fir and iir filters. you can also compare filters using the tool and design and analyze using built in functions.

for implementing filters on embedded hardware, you can convert your filters to fixed point and analyze quantization effects using the dsp system toolbox. you can also implement filters using structures like direct-form fir, overlap-add fir, direct-form ii with second-order sections, cascade all-pass, and lattice structures. you can generate hdl code from filter designs for deployment onto fpgas and asics.
