1MS2T1B1M1QE is a part of Ninigi, an electronic device used in industrial settings. It is designed to provide multiple functions, including analog and digital sound processing, signal amplification, signal encoding and encryption, and interface communication. This part is a multi-stage signal processor which features two sampling-rate converters, one digital signal processor, one microphone pre-amplifier, and one quad EMI filter. The two sample-rate converters provide digital-to-analog (D/A) and analog-to-digital (A/D) conversion, while the digital signal processor offers multi-filter functions, such as low-pass, band-pass, and high-pass filtering. The microphone pre-amplifier provides signal conditioning and amplification, while the quad EMI filter eliminate unwanted signals and noise from entering the system.
