Answer the following statement(s) true (T) or false (F)
1. For maximum transfer of power, the external devices connected to an amplifier must exceed the input and output impedances of the amplifier. 2. A transistor amplifier usually amplifies an AC signal, but first it needs a DC voltage (bias) to supply its operating power. 3. A transistor amplifier configuration is determined by the relationship between the DC input signal and the AC/DC output signal. 4. The common-emitter (CE) is the most widely used amplifier configuration. 5. The common-collector has a low output impedance.
