1 Isibonelo, amandla wesiginali enzwa ngaphansi kokukhulisa okungu-1 ngu-0.1 ~ 1uv, futhi isibonakaliso somsindo sangemuva ngalesi sikhathi naleso sikhulu kakhulu kangangokuba sibhujiswa. Ungayikhipha Kanjani amasiginali awusizo ngangokunokwenzeka futhi wehlise umsindo uyinkinga eyinhloko yokwakhiwa kwenzwa.
2. Isifunda sezinzwa kufanele sibe lula futhi sicwengeke. Uma umsindo ungaphambuki kakhulu kusuka ku-spectrum yesiginali ewusizo, noma ngabe isihlungi sihlungiwe kanjani, lokhu kukhuliswa ngasikhathi sinye. Isilinganiso se-Signal-to-Noise asithuthukiswayo. Ngakho-ke, isekethe yezinzwa kufanele sicwenge futhi silula. Ukuze ugcine i-resistor noma i-capacitor, kufanele isuswe. Lokhu kuyinkinga ukuthi onjiniyela abaningi abaklama izinzwa bavame ukungakunaki. Kuyaziwa ukuthi umjikelezo wezinzwa ukhathazwa yizinkinga zomsindo, futhi lapho umjikelezo uguqulwa khona, kuba yinkimbinkimbi ngokwengeziwe, okuba yindilinga engaziwa.
3. Inkinga yokusebenzisa amandla. Izinzwa zivame ekuqaleni kwemibuthano elandelayo futhi zingadinga ukuxhumana okude isikhathi eside. Lapho ukusetshenziswa kwamandla kwenzwa kukhulu, ukuxhumana kocingo okuholayo kuzokwethula wonke umsindo oholayo namandla, okwenza umklamo wesifunda olandelayo, wenza umklamo wokuhambisa olandelayo, okwenza umklamo wokugcina wokuthenga olandelayo, okwenza umklamo wokuthengisa olandelayo, okwenza umklamo wokugcina we-Moving olandelayo, okwenza umklamo wokugcina wamandla alandelayo, okwenza umklamo wokugcina we-Moving olandelayo, okwenza umklamo wokuthengisa olandelayo, wenza umklamo wesekethe olandelayo ngokwengeziwe. Unganciphisa kanjani ukusetshenziswa kwamandla lapho kwanele futhi kuwuvivinyo olukhulu.
4. Ukukhetha kwezakhi kanye nokujikeleza kwamandla.Ikhetho lezakhi kumele linele, inqobo nje uma izinkomba zedivayisi zingaphakathi kokwakhiwa kwesizungu. Musa ukuphishekela izinkomba zokuhlinzekwa kwamandla ezingafinyeleleki, kepha khetha i-OP AMP nge-Imodi evamile yenqatshwa isilinganiso, bese usebenzisa umjikelezo we-amplifier ohlukile ukuklama ukushintshwa kwamandla okushintsha okuvame ukushintshana nokushintsha.
