A SPLL (software phase-locked loop) is used in this Design Idea to generate a synchronous reference to common-mode powerline interference in two-electrode ECG amplification. Though intended for ECG ...
Hardware-design engineers have long recognized the usefulness of RC lowpass filters (Figure 1). Lowpass filters are useful for performing signal conditioning, removing noise from a signal, or ...
Active filter designers will get a "leg up" with the latest version of FilterPro software. Added features include three premiere filter types, linear phases of 0.05° and 0.5°, support for 12-dB ...
Filter bank design forms a cornerstone of modern digital signal processing, enabling the decomposition of signals into multiple frequency subbands for both analysis and synthesis. Recent advancements ...
Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...
