1.2 Riwayat Hidup Singkat Armein Z. R. Langi di lahirkan di Tomohon, Minahasa, pada tanggal 17 Agustus 1962. Setelah menamatkan SMA pada tahun 1981, Armein Z. R. Langi diterima sebagai mahasiswa ITB pada program studi Teknik Elektro, dan lulus tahun 1987. Ia kemudian menjadi dosen di Laboratorium Sinyal dan Sistem, Departemen Teknik Elektro ITB pada tahun yang sama, dan menjadi peneliti di Pusat Antar Universitas Mikroelektronika (PAU-ME) pada tahun 1989. Oleh PAU-ME, ia dikirim ke University of Manitoba Canada untuk menempuh pendidikan S2 (1990-1992), dan kembali ke ITB. Kemudian, berbekal beasiswa University of Manitoba dan PT INTI, ia melanjutkan studi S3 1993-1996 pada universitas tersebut. Sekembalinya dari Canada, ia menjadi peneliti di PAU-ME dan staf dosen di Departemen Teknik Elektro ITB (sekarang Sekolah Teknik Elektro dan Informatika, STEI). Riwayat hidup dan pekerjaan terdiri dari: 1. Riwayat Hidup, Pendidikan, dan Pekerjaan. 2. Riwayat Kegiatan Akademis dan Riset 3. Riwayat Kegiatan Inovasi dan Industri 4. Riwayat Kegiatan Pengabdian Masyarakat Minat topik riset diawali tahun 1985 dengan desain embedded system berbasis prosesor mikro Z80, yang dilanjutkan dengan sistem akusisi data berbasis IBM-XT di tahun 1987. Minat riset berkembang menuju sistem pemrosesan sinyal digital (DSP) pada tahun 1988 menggunakan prosesor DSP TMS320C25. Pada tahun 1990, riset dilanjutkan dengan desain hardware FPGA serta algoritma pemampatan ucapan LPC dan CELP. Sebuah sistem waktu-nyata CELP diimplementasikan pada TMS320C30. Minat berkembang menjadi pemampatan sinyal multimedia (ucapan, citra, dan video) serta pemrosesan sinyal menggunakan transformasi Fourier, wavelets, serta multifractals. Di tahun 1994 paper mengenai wavelet terpilih sebagai paper terbaik untuk diterbitkan IEEE Technology Series. Pada tahun 1996 menulis disertasi mengenai multifractal prrocessing pada sinyal non stasioner. Saat ini minat riset yang ditekuni adalah pengembangan smart engineering menggunakan teknologi informasi dari sistem pemrosesan sinyal.
