Is digital TV immune to these analogue problems?
DVB-T uses QAM, which is susceptible to phase problems. However, given that the information is digital, a decent tuner stands a much better chance of filtering out the weaker component. You definitely won't see ghost images: either your bit-error rate is too high for the built-in redundant coding, or it isn't. So either you get MPEG decoding errors, or you don't.
