IMF250 DIGITAL FILTER
Achieve difficult filter characteristics with digital signal processing that are challenging with analog filters [custom orders available]. Palm-sized with excellent portability!
This is a compact and lightweight digital filter that allows for the removal and extraction of signals by setting and selecting necessary characteristics. This device is a digital filter that restricts the frequency band of signals, realized through digital signal processing. In addition to operating independently, it can be controlled from PC application software via a USB interface. You can select from 64 types of characteristics using the dip switches on the device panel or through the PC application. The 64 filter characteristics can be connected in series, allowing for a band-pass characteristic using HPF + LPF. The characteristics can be swapped, and by loading characteristic files, different characteristics can be achieved. It is also possible to execute arbitrary filter coefficients directly, making it a highly flexible filtering device. It can operate in a local state, functioning solely on the device, or in a remote state, configured from a PC. By connecting an external power source, such as a mobile battery, to the USB power connector to supply 5V, it can operate independently. When connecting to a PC via the USB communication connector, it can operate using USB bus power. Custom specifications are available.
