Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

Class D amplifiers are revolutionizing the audiophile world, delivering top-tier sound without the hefty price tag. Discover how brands like NAD, Topping, and SMSL are making high-quality audio ...

Embedded electronics has continued to ramp up across the automotive landscape, taking on more substantial roles in many applications. One example is the presence of multiple class-D audio amplifiers ...
