A while ago, I wanted to experiment with a simple audio frequency filter measurement setup, but surprisingly, my lab is still missing a swept signal source. As I contemplated a quick and dirty ...

This brief paper examines the most important differences between the responses of the Fast Fourier Transform (FFT) and Polyphase Discrete Fourier Transform (DFT) filter banks. In general, while the ...

Filters are used in many applications to remove unwanted frequency components from incoming signals, enhance incoming signals, or both. In portable and non-portable medical applications, for example, ...

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 ...

To correct oscillations in a machine,mechanical design improvements and electronic filters are typically employed.However, these solutions often deliver limited success. Engineers should ...

Murata Manufacturing has begun mass production and commercial shipment of the first high-frequency filter to use XBAR technology. First high-frequency filter to use XBAR technology goes into ...
