Anplifikatè yo klase kòm A, AB, B, C, D ak E. Klas la reprezante kantite lajan an nan varyasyon yon siyal pwodiksyon gen plis pase yon sik si opinyon an se yon ond sinuzoido. lineyè nan plis yon anplifikatè se, pi ba a pwodwi a distòsyon. Klas A ki pi lineyè a ak klas C se pi piti a lineyè. Klas C se pa apwopriye pou aplikasyon pou odyo ak tipikman yo itilize nan pwodwi tankou transmeteur RF. Klas D ak E yo oblije chanje anplifikatè ki ka itilize etap pwodiksyon kous ki gen rezonateur Harmony, plizyè oblije chanje tren ekipman pou, teknik pwodiksyon flater, ak PWM ak delta-sigma batman ogmante efikasite ak rekonstwi ond nan opinyon nan pwodiksyon an.

Amplifiers are classified as A, AB, B, C, D and E. The class represents the amount of variation an output signal has over one cycle if the input is a sinusoidal waveform. The more linear an amplifier is, the lower the distortion product. Class A is the most linear and class C is the least linear. Class C is not suitable for audio applications and typically is used in products like RF transmitters. Classes D and E are switching amplifiers that can utilize output circuit stages containing harmonic resonators, multiple supply rail switching, complimentary output techniques, and PWM and delta-sigma modulation to increase efficiency and reconstruct the input waveform at the output.
