CLASSIFICATION OF BIOELECTRIC SIGNALS AND THEIR CHARACTERISTICS Abstract. Most medical research requires long-term monitoring of the patient's condition,
which is associated with the need to use automated systems for recording biomedical signals, processing them to assess functional changes in the body and analyzing large amounts of data to form a strategy for the treatment process.
Biosignals are physical manifestations of the physiological processes of a living organism, which can be measured and presented in a form convenient for further processing. Processing of biosignals is carried out in order to highlight informative features for medical diagnostics.

KIRISH
Axborotlashtirishning ilg‘or yo‘nalishlaridan biri tibbiyot sohasida kompyuterlashtirishdan iborat. Tibbiyot amaliyotida kompyuterni o‘lchash va nazorat qilish uskunalari bilan birgalikda qo‘llash bemorning ahvoli to‘g‘risidagi ma‘lumotlarni avtomatlashtirilgan holda yig‘ish va uni real vaqt rejimida qayta ishlash uchun yangi samarali vositalarni yaratish imkonini bermoqda [1].
So‘nggi yillarda biosignallardan foydalanish zamonaviy jamiyatning ko‘plab sohalarini qamrab olmoqda.
TADQIQOT MATERIALLARI VA METODOLOGIYASI
Elektr biosignallari yoki bioelektrik vaqt signallari odatda asab tizimi maxsus to‘qima, organ yoki hujayra tizimidagi elektr potentsial farqining yig‘indisi natijasida hosil bo‘lgan elektr tokining o‘zgarishini anglatadi. Tibbiyot sohasida qo‘llanilayotgan biosignallar quyidagilardan iboratdir:
EKG (elektrokardiografiya);
spirografiya (tashqi nafas olish funktsiyasini tekshirish); EKG va qon bosimining kunlik monitoringi; EEG (elektroensefalografiya);
Terining galvanik reaktsiyasi (GSR) yoki elektrodermal faollik (EDA); shuningdek stress testlari.
Bulardan tashqari nafas olish funktsiyasini, miya faoliyatini, qon aylanishini, asab tizimining holatini va yurakni baholashga imkon beruvchi murakkabroq tadqiqotlar tizimi mavjud [2].
