While spread-spectrum clocking has long since been used in processor and memory clock trees, there are many other clocked systems, such as power supplies or switch-mode amplifiers, that continue to use a single-frequency clock. This can, in turn, generate significant EMI and can make meeting governmental regulations for EMI challenging. These regulations typically set a limit on peak energy within

Digital filtering is an integral part of many digital signal processing algorithms. Digital filters are characterized as either recursive [infinite impulse response (IIR)] or non-recursive [finite impulse response (FIR)] filters. IIR filters require a smaller order for the same set of specifications compared to FIR filters, while FIR filters provide a linear phase property. However, IIR filters, i
