మొదటి యాంప్లిఫైయర్ యొక్క లాభం, V1 = 10
రెండవ యాంప్లిఫైయర్ యొక్క లాభం, V2 = 25
రెండు-దశల క్యాస్కేడ్ యాంప్లిఫైయర్ యొక్క మొత్తం వోల్టేజ్ లాభం రెండు దశల వోల్టేజ్ లాభాల ఉత్పత్తి ద్వారా ఇవ్వబడుతుంది, అనగా,
V = V1 x V2
= 250
ఇన్పుట్ సిగ్నల్ వోల్టేజ్, Vi = 10 mV=0.01 V
రెండవ దశ యొక్క అవుట్పుట్ = Vo
⇒ Vo=2.5 V
