sdr.FIRInterpolator(taps: ArrayLike, rate: int, streaming: bool = False) Creates a polyphase FIR interpolating filter with feedforward coefficients \(h_i\). Parameters:¶ taps: ArrayLike¶The feedforward coefficients \(h_i\). rate: int¶The interpolation rate \(r\). streaming: bool = False¶Indicates whether to use streaming mode. In streaming mode, previous inputs are preserved between calls to filter().
