Delay time will be a constant but shifted phase will be depand on frequency. No matter you design a circuit to shift phase of tone. But it's nearly improsible to shift a board band analog signal in a same vaule of phase. If the boardband signal be modulated by another signal then it's a different story... Regards, Wenye
