Download Solution PDFसमाधान:
पहले एम्पलीफायर का लाभ, V1 = 10
दूसरे एम्पलीफायर का लाभ, V2 = 25
दो चरण वाले कैस्केड एम्पलीफायर का कुल वोल्टेज लाभ दोनों चरणों के वोल्टेज लाभ के गुणनफल द्वारा दिया जाता है, अर्थात,
V = V1 × V2
= 250
इनपुट सिग्नल वोल्टेज, Vi = 10 mV=0.01 V
माना दूसरे चरण का आउटपुट = Vo
⇒ Vo=2.5 V
