Sesefa se Matla sa Harmonic (AHF)—Mokhahlelo o le Mong
Kakaretso ea Sehlahisoa:
Li-filters tse sebetsang tsa harmonic (AHF) ke karabo ea ho qetela mathateng a boleng ba matla a bakoang ke ho sotha ha waveform, matla a tlase, phapang ea motlakase, ho fetoha ha motlakase le ho se leka-lekane ha meroalo bakeng sa likarolo le lits'ebetso tse fapaneng.Ke mofuta o phahameng oa ts'ebetso, o kopaneng, o feto-fetohang, oa modular le o bolokang chelete e ngata oa li-filters tsa matla tse sebetsang (APF) tse fanang ka karabelo ea hang-hang le e sebetsang mathateng a boleng ba matla lits'ebetsong tsa matla a motlakase a tlase kapa a phahameng.Li thusa nako e telele ea bophelo ba lisebelisoa, ts'epahalo e phahameng ea ts'ebetso, matla a ntlafatso a sistimi le botsitso, le tahlehelo e fokotsehileng ea matla, e tsamaellanang le litekanyetso tse boima tsa boleng ba matla le likhoutu tsa grid.
