The article investigates the role of small-signal bandwidths in a communication era where big bandwidths predominate. According to the author, a lot of operational amplifiers include a small-signal bandwidth specification in their data sheets. Manufacturers base specifications on signal amplitudes that are approximately 0.1V. Applications can take advantage of small-signal bandwidths that can be greater than the large-signal bandwidth since the op amp is operating at midrange, the author adds.

    A study of different distortions in high-speed differential PAM-4 signals, including the linear distortions, i.e. amplitude mismatch, channel skew and bandwidth mismatch, and the non-linear distortion, i.e. the mismatch between rising and falling edges is presented. It is observed that only the...

    A definition of the term "Single-Sideband Modulation" (SSB) is presented. It refers to a refinement of the technique of amplitude modulation designed to be more efficient in its use of electrical power and bandwidth. SSB is closely related to vestigial sideband modulation (VSB). A filter removes...
