Selecting resistors for high-end audio applications

摘要

ONE OF THE BEST WAYS to avoid or minimize noise and distortion in the signal path of high-end audio applications is the careful selection of resistors. This paper describes the noise generation in resistors manufactured using the various available resistor technologies and quantifies the noise insertion typical for each type. Noise is an unwanted wide-spectrum signal that may be superimposed on any useful signal, including dc.
