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 […]

An undesirable pattern that appears when a graphic image is displayed or printed with an inappropriate resolution. Moiré patterns are difficult to predict because they result from a complex combination of parameters: the size of the image, resolution of the image, resolution of the output device, halftone screen angle, etc. If you’re planning to print […]
