"The UK uses UHF for terrestrial television transmissions, with both PAL-I analogue broadcasts and DVB-T digital broadcasts sharing the band. The following table is a handy channel/frequency conversion table showing the E channel number, PAL-I vision and sound carrier frequencies, and the centre frequency for digital tuning. Explainer The frequency plan for the UK involves each channel having an 8MHz bandwidth - the space in the spectrum that each channel is allotted. The PAL-I standard specifies a video bandwidth of 5.0 MHz and an audio carrier at 6 MHz. The DVB-T transmissions must fall within this channel plan, resulting in each digital channel also having a bandwidth of 8 MHz. Unlike PAL-I, the digital channel (carrying a multiplexed signal) utilises the entire bandwidth available to it simultaneously, transmitting 2048 carriers (in &amp;quot;2k mode&amp;quot;). For tuning purposes, a centre frequency is used.
