Kuwedzeredza chiyero chekugona kwechikwata chemasuo maviri (kazhinji chinosimudzira) kuwedzera simba kana amplitude yechiratidzo kubva pakupinda kuenda kuchiteshi chekuburitsa nekuwedzera simba rakashandurwa kubva kune imwe simba rekupa simba kuchiratidzo. Inowanzo tsanangurwa seyakaenzana chiyero chechiratidzo amplitude kana simba pachiteshi chekuburitsa kune amplitude kana simba pachiteshi chekupinda. Inowanzo kuratidzwa uchishandisa logarithmic decibel (dB) mayuniti ("dB gain"). Kuwedzeredza kwakakura kupfuura imwe (yakakura kupfuura zero dB), ndiko kuwedzera, ndiyo tsananguro yemunhu anoshanda kana wedunhu, nepo passive gain ichave nekuwedzeredza isingasviki imwe. Izwi rekuwedzera roga harina kujeka, uye rinogona kureva chiyero chekuburitsa kune voltage (voltage), ikozvino (current) kana h (current) simba rekuwedzera. Mune mashandiro emagetsi emagetsi uye masimba emagetsi anochinjika kubva kune imwe simba rekupa simba kuenda kuchiratidzo.
