🔍 Key Concepts

• Definition of a pure amplifier in electronics/communications • What is meant by "form of the input and output energy" • Meaning of ratio of output change to input change (gain) and whether it must be greater than 1

💭 Think About

• Think about what makes an amplifier different from a converter or modulator: does it change the type of energy or just its magnitude? • Ask yourself if an amplifier can have a gain less than 1 and still be considered an amplifier in some contexts, or if the definition strictly requires gain greater than 1 • Consider whether the question is asking about what is always true (mandatory) or what is only sometimes true

✅ Before You Answer

• Be clear on whether a pure amplifier is required to preserve the waveform/form of the signal (same type of energy in and out) • Verify if gain > 1 is an absolute requirement in the formal definition, or if gain can be equal to or less than 1 in certain amplifier stages or conditions • Check which statement(s), I or II, meet the idea of a "mandatory operating characteristic" rather than just a typical characteristic
