Tšebeliso ea lisebelisoa tsa phetoho ea mekhahlelo (PCMs) liindastering tse ngata li bontša hore li na le menyetla e pharaletseng le menyetla e hlakileng ea tsoelo-pele ea bokamoso.Lisebelisoa tsena li bohlokoa haholo bakeng sa bokhoni ba tsona ba ho monya le ho lokolla mocheso o mongata nakong ea liphetoho tsa mekhahlelo.Lintlha tse latelang ke likarolo tse 'maloa tsa bohlokoa le litebello tsa nts'etsopele ea nako e tlang ea lisebelisoa tsa phetoho ea karolo:
1. Matla a matla le boqapi
Lefapheng la meralo ea meralo, li-PCM li ka sebelisoa e le karolo ea litsamaiso tse bohlale tsa taolo ea mocheso ho fokotsa ho its'etleha ho futhumatsang setso le moea.Ka ho kopanya li-PCM linthong tsa ho haha tse kang marako, marulelo, fatše, kapa lifensetere, ho sebetsa hantle ha mocheso mehahong ho ka ntlafatsoa haholo, tšebeliso ea matla e ka fokotsoa, ’me ho ntšoa ha likhase tse futhumatsang lefatše ho ka fokotsoa.Nakong e tlang, ka nts'etsopele ea lisebelisoa tse ncha le tse sebetsang tsa phetoho ea mekhahlelo le ho fokotsa litšenyehelo, kopo ena e ka 'na ea ata haholo.
2. Litsamaiso tsa matla a tsosolositsoeng
Lits'ebetsong tsa matla a tsosolositsoeng tse kang matla a letsatsi le moea, li-PCM li ka sebetsa e le mecha ea ho boloka matla ho leka-lekanya phepelo le tlhokahalo.Ka mohlala, matla a mocheso a hlahisoang ke mekhoa ea ho kotula matla a letsatsi motšehare a ka bolokoa ho PCM 'me a lokolloa bosiu kapa nakong ea tlhokahalo e phahameng.Sena se thusa ho ntlafatsa katleho ea tšebeliso ea matla le ho netefatsa tsoelo-pele ea phepelo ea matla.
3. Taolo ea mocheso oa lihlahisoa tsa elektronike
Ha lisebelisoa tsa elektronike li ntse li eketseha le ho sebetsa ka mokhoa o phahameng, ho felisa mocheso ho fetohile phephetso e kholo.Li-PCM li ka sebelisoa lihlahisoa tsa elektroniki tse kang li-processor tsa khomphutha le lisebelisoa tsa mehala ho thusa ho laola meroalo ea mocheso, ho lelefatsa nako ea bophelo ba sesebelisoa, le ho ntlafatsa ts'ebetso.
4. Liaparo le Liaparo
