1. While an amplifier is used to increase the value of the input voltage, it also amplifies the noise present in the signal. This is because all electronic amplifiers have a certain level of inherent noise that gets added to the signal as it is amplified. However, modern amplifiers are designed with techniques to reduce this noise and provide a clean amplified output.
2. While the maximum grid voltage is produced in one tube, the other tubes in the amplifier circuit can also contribute to the overall amplification process. This is because in certain amplifier configurations, multiple tubes are connected in parallel or in cascade to achieve a higher overall amplification gain. Each tube plays a specific role in the amplification process and contributes to the final amplified output.
3. While direct current plate components are eliminated in an amplifier circuit, it is important to ensure that the alternating current (AC) signal is properly amplified. This is because direct current (DC) does not carry any audio information and needs to be removed from the signal to avoid distortion and other issues. AC signals, on the other hand, carry the desired audio information and need to be amplified accurately without any loss or distortion.
In summary, while an amplifier is used to increase the value of the input voltage, it also amplifies noise. The maximum grid voltage produced in one tube can be supported by other tubes in the circuit, and direct current plate components are eliminated to ensure accurate amplification of the alternating current signal.
