Mata kuliah Elektronika Terapan mempelajari tentang pengantar penguat instrumentasi (operational amplifier), detektor penyilang nol (zero-crossing detector), detektor taraf tegangan (voltage level detector), umpan balik negatif (negative feedback), umpan balik positif (positive feedback), penguat pembalik (inverting amplifier), penguat tak-pembalik (non-inverting amplifier), penguat diferensial (differential amplifier), penguat instrumentasi (instrumentation amplifier), integrator, komparator (comparator), diferensiator (differentiator), serta operational amplifier sebagai histeresis (Schmitt trigger).
