DIGITAL FILTER FOR TELEMETERING

摘要

The filter includes a filter coefficient generating and share memory managing means (11) consisting of a CPU and a share memory (12). A multibus (1) is connected to the managing means (11), while a control bus (2), an address bus (3) and a data bus (4) are connected to the multibus (3). A band removing filter means (13), a band pass filter means (15) and an input/output eans (17) are connected to the control bus (2), the address bus (3) and the data bus (4) respectively. Analogue/digital converting means (14, 16, 18) are connected to the band removing filter means (13), the band pass filter means (15) and the input/output means (17) respectively. The filter makes it possible to vary the shielding frequency and the band width.
