Final answer:
An ideal amplifier should have zero output impedance, not infinite output impedance, to ensure maximum power transfer to the load; infinite output impedance would hinder its function.
Step-by-step explanation:
Among the options provided for the characteristics of an ideal amplifier, the one that does not align with the concept of an ideal amplifier is d. infinite output impedance. In fact, an ideal amplifier would have a zero output impedance to ensure maximum power transfer to the load. Here's a breakdown of the ideal characteristics:
- Infinite bandwidth: This is desired so the amplifier can handle a wide range of frequencies without limitations.
- Infinite gain: To amplify signals to any level without loss of signal quality.
- Infinite input impedance: To avoid loading the source and ensure that the maximum voltage is presented to the amplifier.
- Infinite output impedance: This is undesirable because it would mean no current could flow to the load, which contradicts the purpose of amplification.
Overall, while the other characteristics contribute to the sensitivity and effectiveness of an amplifier, an infinite output impedance would in fact hinder its function.
