Digital-PWM audio power amplifiers with noise and ripple shaping. This paper presents a digital pulse width modulation (PWM) technique featuring noise and ripple shaping for audio power amplification. The sampled power-source amplitude signal is used to shape the interpolated input digital signal, which is fed to a noise shaper to produce a ...

"An audio power amplifier (or power amp) is an electronic amplifier that strengthens low-power, inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving loudspeakers or headphones.". This includes both amplifiers used in home audio systems and musical instrument amplifiers like guitar amplifiers.

The audio power amplifier is a kind of electronic amplifiers that amplify low-power audio signals (the frequencies of the low-power signals are always between 20 Hz to 20 KHz) to a level that can be suitable for driving the loudspeakers. Nowadays all types of electronics that could make sounds are widely using the audio power amplifier, such as ...

1.3 Gain Setting for the Audio Power Amplifier It is also imperative to understand that the output signal from the CODEC or DAC driving the audio power amplifier should be as large as possible, to have a high SNR. Conversely, the gain of the audio power amplifier is set as low as possible. If the audio power amplifier’s gain is set

Power Amplifiers are the Worst Offenders. The power supplies in high power devices, such as audio power amplifiers, can emit very strong magnetic fields. These strong fields tend to limit the noise performance (SNR) of power amplifiers. These magnetic fields can also cause interference with audio products that happen to be too near the amplifier.
