Cable TV channel frequencies

This page on television basics tutorial covers cable TV channel frequencies. It mentions channel-2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, channel A-2, A-1, A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, channel-W and Channel-AA to Channel-RR.

As we know microwave frequencies can not be transmitted over the cable. In order to transmit these high frequency signals over cable they are downconverted to lower frequencies using mixers. Few of these channels are mapped to standard 6MHz TV channel frequencies.

The cable TV channel frequencies are nonbroadcast channels. Heterodyne processors are employed to translate received signals to the desired channels. The processor will have tuner which will pick the over the air signals and produce channels with IFs of about 45.75 and 41.25 MHz. These picture and sound IFs are separated by filters and passed through AGC circuits to provide gain.
