Systems and Methods for Low Pass Filter Mismatch Calibration

System and methods are provided for calibration of low pass filter mismatch. An example system includes: a tone generator configured to generate a tone signal with a baseband frequency value; one or more low pass filters configured to filter one or more analog signals associated with the tone signal; one or more analog-to-digital converters (ADCs) configured to generate one or more aliases associated with the one or more analog signals; and a calibration processor configured to detect low pass filter mismatch based at least in part on the one or more aliases associated with the tone signal. 提供了用于低通滤波器失配校准的系统与方法。示例性系统包括：音频发生器，被配置为生成具有基带频率值的音频信号；个或多个低通滤波器，被配置为对与音频信号相关联的个或多个模拟信号进行滤波；个或多个模数转换器(ADC)，被配置为生成与个或多个模拟信号相关联的个或多个假频；以及校准处理器，被配置为至少部分地基于与音频信号相关联的个或多个假频来检测低通滤波器失配。
