Before Change

    if pad:
        padding         = [(0, 0)]  * data.ndim
        padding[axis]   = (order, 0)
        delta_x              = np.pad(delta_x, padding, mode="constant")

    return delta_x

After Change

        delta_x     = scipy.signal.lfilter(window, 1, delta_x, axis=axis)
    
    if trim:
        idx         = [Ellipsis] * delta_x.ndim
        idx[axis]   = slice(half_length, -half_length)
        delta_x     = delta_x[idx]
    
    return delta_x
