🔍 Key Concepts

• Meaning of beta (β) in a bipolar junction transistor (BJT) • Definition of cutoff frequency or -3 dB point and the 0.707 factor • Which transistor terminal currents are related to β in a BJT (base, collector, emitter)

💭 Think About

• First, recall what β represents in a BJT: it is the ratio of which current to which current? • At the beta cutoff frequency, what happens to that current gain compared to its low-frequency (maximum) value? Think about the standard -3 dB point. • Look at each option and ask: does this option correctly pair the right current with β and the 0.707 factor?

✅ Before You Answer

• Verify which terminal current gain is actually called β in a BJT (base, collector, or emitter). • Remember that the cutoff frequency is commonly defined where gain falls to 0.707 of its maximum (the -3 dB point). • Eliminate any choices that mention a terminal type that does not exist in a BJT or that misuse the term β.
