Bridged T delay equaliser

The circuit described does not sound anything like a bridged T delay equaliser (which is where the wikilink goes). Replacing the inductors with resistors will kill the mutual coupling which is largely responsible for the delay. It will also no longer have an all-pass response, the central feature of delay equalisers. The text claims that this will result in a notch filter. It doesn't look like that is the case to me, just a gentle attenuation towards low frequencies, but I would need to see the actual circuit to be sure. This may be some sort of bridged T circuit, but again, an actual circuit will clear this up. Hard to see where three capacitors came from. There are only two in the bridged T delay equaliser.
