最大限度地减少总谐波失真音频系统中的模拟开关贡献

摘要：常用的音频系统使用模拟开关切换低级别的输入或调整音频过滤器的特点。选择合适的模拟开关，可以帮助优化系统的总谐波失真（THD），在设计师的成本预算。

Minimizing Total Harmonic Distortion Contributed by Analog
Switches in Audio Systems

Abstract: Analog switches are commonly used in audio systems to switch low-level inputs or adjust audio filter
characteristics. Selecting the proper analog switch can help optimize the total harmonic distortion (THD) of a
system within the designer's cost budget.
