IMF250 Digital Filter, IMF240 Analog Filter
Attenuates unwanted signals by 100dB. Steep characteristics of 60dB/oct to 100dB/oct. Compact palm-sized design for excellent portability.
Signal preprocessing is important for data analysis. A signal filter developed by Intermind in conjunction with a low-noise preamplifier (IMP series). It attenuates unwanted signals by 100dB, with steep characteristics ranging from 60dB/oct to 100dB/oct. Compact and palm-sized for excellent portability. - Digital filter achieving steep characteristics ⇒ IMF250 - Analog filter achieving low noise ⇒ IMF240 【IMF250】 Operates independently and can be controlled via a PC application through USB. Select from 64 types of characteristics using the dip switches on the panel or the PC application. The 64 filter characteristics can be connected in series to achieve band-pass characteristics using HPF + LPF. It is also possible to execute arbitrary filter coefficients directly. Can operate on a mobile battery or USB bus power. 【IMF240】 Low noise, configured with high-pass and low-pass filters. Compact and lightweight. Custom specifications are available. Our company offers custom contract development for low-noise circuits, analog circuits, filter circuits, signal processing circuits, and circuit design. Please feel free to contact us.

Our company is a proposal-based prototype development specialist manufacturer that develops custom electronic devices and the systems that connect them. We realize "measuring, thinking, and connecting" with unique ideas to meet our customers' needs. Please feel free to consult us about anything, whether it's "I want to make this," "I'm having trouble," or "I want to improve this." To materialize our customers' new ideas, we provide proposals and support through manufacturing. By using custom products that align with your company's values instead of fitting your values to off-the-shelf products, we lead you to high-value work. This enhances your company's value and increases productivity. It is our pleasure to respect diversity and provide and support such electronic devices. Sensors capture various phenomena, low-noise analog circuits process the reality as perceived by humans, digital signal processing performs analysis and feature extraction, and interfaces communicate the necessary results to people. The fields where we can apply our expertise in hardware/software signal processing are broad, and we continue to challenge ourselves in custom manufacturing and real-time processing based on our extensive development achievements and proprietary technologies.
