    Fast Fourier transform-based implementations of the discrete Fourier transform have proven themselves the workhorses of discrete-time spectral analysis. Although these algorithms find widespread use, they have limitations. One problem is that frequency resolution is dependent on the number of samples available. For a given sampling frequency, the longer the data record, the better the frequency re... View full abstract»

    With the explosion in the popularity of cable and digital subscriber line modems for high-speed Internet access, the odds are that there will be one of these broadband communications devices in many homes or offices. The odds are that the chips inside the modem will have been designed by Broadcom Corp., and be based on digital signal-processing (DSP) architectures conceived by Henry Samueli. The a...

    This article on signal integrity has been approached from a slightly different angle than that normally pursued. There is an abundance of material on general signal integrity. Instead of repeating textbook techniques, however, the focus has been on two important issues: visualization, to assist intuition; and the basics of defensive design, which helps the designer get his or her design right the ...

    The process of engineering systems on a chip will transform relationships among hardware, software, and mechanical designers. Various issues in systems engineering are discussed as is the role of systems engineering as a process. Co-design objectives and the state of co-design in electronic design automation are then considered as are virtual system prototypes View full abstract»
