modulate
To blend data into a carrier signal. At the receiving side, a device demodulates the signals by separating the constant carrier signals from the variable data signals. For example, radio uses two types of modulation – amplitude modulation (AM) and frequency modulation (FM) – to mix audio signals with an AM or FM carrier signal. A modem modulates data by converting it to audible tones that can be transmitted on a telephone wire, and demodulates received signals to get the data.

- modulation fallback
When signals are transmitted from one modem to another, each modem interfaces at a specific speed. If one modem communicates at a faster rate than the modem at the other end, then the faster modem falls back to a slower modulation. For example, if a user connects to the Internet using a 14000-bps modem and […]
