Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Most embedded engineers writing firmware have used some sort of digital filters to clean up data coming from various inputs such as ADCs, sensors with digital outputs, other processors, etc. Many ...

Unlike conventional analog signal processing in which signals can be any value between a minimum to maximum and occur continuously in time – digital signal processing uses a finite precision in ...
