sdr.FIR.filter(x: ArrayLike, mode: Literal[full] | Literal[valid] | Literal[same] = 'full') → ndarray Filters the input signal \(x[n]\) with the FIR filter. Parameters:¶ x: ArrayLike¶The input signal \(x[n]\). mode: Literal[full] | Literal[valid] | Literal[same] = 'full'¶The convolution mode. See scipy.signal.convolve() for details. Returns:¶ The filtered signal \(y[n]\). Examples¶ See the FIR filters example.
