WebbThis type of trade-off exists in image scaling as well as audio filtering, if that's more familiar to you. There's also the linear phase filters, which have a symmetrical impulse response, and the minimum phase ones, which have no pre ringing. The linear filters have no group delay (all frequencies have the same delay), so that is considered good.
