スペクトラ List of Products and Services

Spectra Inc. assists with circuit board design based on signal processing technology, as well as DSP software design, FPGA circuit design, and PC application design. Since we do not specify application fields, we have a wealth of development experience, and if you provide us with implementation and operational images, we will consider creating specifications from there. We will examine the feasibility of the specifications and, if realization is difficult, we will propose as many methods as possible. We can also handle partial processes. We support hardware and software development for various applications. 【Business Overview】 ■ Development, manufacturing, and sales of hardware and software for electronics and mechatronics devices. *For more details, please refer to the PDF materials or feel free to contact us.

• Embedded system design service

We would like to introduce a development case of the "Digital Communication Modem" commissioned by Spectra Inc. Regarding the DSP software for communication modems, we received requests to implement equivalent functions to the DSP due to the discontinuation of the modem IC used in existing devices. Through our development, we achieved the implementation of modulation and demodulation methods in accordance with standards, as well as the development and optimization of algorithms tailored to actual usage environments. 【Case Details】 ■ Subject: DSP Software for Communication Modems ■ Customer Requests - Due to the discontinuation of the modem IC used in existing devices, we want to implement equivalent functions to the DSP. - New implementation of additional features. - Software support for switching modulation methods (support for multiple modulation methods). - Verification of combined operation with other devices (repeaters, etc.) used in real environments. *For more details, please refer to the PDF document or feel free to contact us.

• Embedded system design service

We would like to introduce a development case of the "Image Inspection Device" commissioned by Spectra Co., Ltd. We received a request regarding the substrate for agricultural product image inspection and discrimination devices, aiming to reduce the current inspection and discrimination processing time from about 30 seconds to approximately 5 seconds. Through our development, we optimized the image processing algorithm provided by the client. Additionally, we reduced computation time through algorithm optimization and parallel processing, achieving the client's desired processing time. 【Case Details】 ■ Target: Substrate for agricultural product image inspection and discrimination devices ■ Client Requests - Reduce the current inspection and discrimination processing time from about 30 seconds to approximately 5 seconds - Save inspection results and image data on the substrate - I/F (USB, Bluetooth), PC application *For more details, please refer to the PDF document or feel free to contact us.

• Embedded system design service

We would like to introduce a development case of the "Voice Detection Method VOX" commissioned by Spectra Co., Ltd. Regarding the Voice Detection Method VOX (voice-activated switch), there was a request to create a VOX function that does not malfunction in environments with high noise (low S/N). Through our development, we achieved a DSP implementation of a high-precision discrimination algorithm for noise and voice using feature extraction of voice characteristics. 【Case Details】 ■ Subject: Voice Detection Method VOX (voice-activated switch) ■ Client Requests - VOX function that does not malfunction in high noise (low S/N) environments - DSP implementation *For more details, please refer to the PDF document or feel free to contact us.
