The second issue is that phase equalization is essential for an analog television signal.  Without it [[material dispersion|dispersion]] causes the loss of integrity of the original waveshape and is seen as smearing of what were originally sharp edges in the picture.

=== Digital telecommunications ===

{{main|Equalizer (communications)}}⏎
Modern digital telephone systems have less trouble in the voice frequency range as only the local line to the subscriber now remains in analog format, but [[Digital Subscriber Line|DSL]] circuits operating in the [[MegaHertz|MHz]] range on those same wires may suffer severe [[attenuation distortion]], which is dealt with by automatic equalization or by abandoning the worst frequencies.  [[Videophone|Picturephone]] circuits also had equalizers.
