Signal transmitting system, signal processing system and method thereof

The invention discloses a signal transmitting system, a signal processing system and a method thereof. A frequency dependent dynamic range control method is used in a signal transmission system having a lower impedance in the high frequency region, whereby the current spectrum is dynamically estimated and the adjustment parameters are adjusted to reduce the current in the high frequency region. This approach advantageously avoids current overload without the need to use a series resistor as a current limiter. 本申请公开一种信号发射系统、信号处理系统及其方法。频率相关的动态范围控制方法使用于在高频区域具有较低阻抗的信号发射系统中，借此动态估计电流频谱和调节参数以降低高频区域中的电流。此方法有利地避免了电流过载而不需使用串联电阻器作为电流限制器。
