BJT 多級放大電路

BJT Multi-stage Amplifer

This experiment will practice cascading multiple BJT amplifiers, observe the impact of multi-stage circuit structures on voltage gain and bandwidth, and listen to the microphone signal amplified by this amplifier. 

本次實驗將練習串聯多個 BJT 放大電路，觀察多級的電路結構，如何影響電壓增益、頻寬。並且聆聽透過這個放大器放大之後的麥克風訊號。
