TMS320F280049: tidm_02002 中低通滤波器的截止频率怎样计算

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE

在C:\ti\c2000\C2000Ware_DigitalPower_SDK_3_02_00_00\solutions\tidm_02002例程中有这样一个滤波器

//! \brief Run EMAVG module
//! \param v The EMAVG structure
//! \param in Input
//!
static inline void EMAVG_run(EMAVG *v,float in)
{
v->out = ((in - v->out)*v->multiplier) + v->out;
}

我想知道:

1)当滤波参数设定为0.01,采样周期为100us时,该滤波器的截止频率是多少,怎样计算的?
