WebbTo realize higher-order filters, biquad sections can be cascaded. The Need for Complex Poles We typically begin the design of filters by deciding on the order and shape of their frequency response. For example, Wi-Fi receivers commonly employ a fifth-order LPF to suppress unwanted channels. http://vlabs.iitkgp.ac.in/asnm/exp30/index.html
