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 AUX-0025 filter instrument may answer the measurement demands of chip designers and switching-amp manufacturers for an accurate and repeatable solution. Audio Precision's Class D, Class I, Class S ...
Sound can be represented with both analog or digital audio signals. Analog audio signals use electrical voltage levels. Different types of transducers convert sound to electrical signals and ...
The filter type can be described in several different ways. Low-pass and high-pass filters in two-way crossover networks are often identified by their "Q". The Q is the resonance magnification of the ...
Introduction It is often necessary to filter data from sensors or audio streams in order to suppress unwanted noise. And, most of the time, a simple first order filter is all that is required. The ...
