When dialing from a land-line telephone, the telephone number is encoded and transmitted across the telephone line in form of dual-tone multi-frequency signaling (DTMF). The tones control the telephone system by instructing the telephone switch where to route the call. These control tones are sent over the same channel, the copper wire, and in the frequency range (300 Hz to 3.4 kHz) as the audio of the telephone call. In-band signaling is also used on older telephone carrier system… WebFrequency 5785 MHz is the image frequency of 3700 MHz. This has been derived from, Fimage = 3700 + 2*(1042.5) = 5785 MHz. Here IF of 1042.5 MHz is used as per heterodyne down converter diagram shown below.
