... The AM and FM detector circuits are shown in Figure 9. The FM detector (or “demodulator,” to use a more accurate, modern term) is implemented as a ratio detector. This detector is advantageous as it does not require a separate limiter circuit to remove amplitude variations. The ratio detector accomp ...

Cellular repeater

A cellular repeater (also known as cell phone signal booster or amplifier), in the cell phone industry, is a device used for boosting the cell phone reception to the local area by the usage of a reception antenna, a signal amplifier, and an internal rebroadcast antenna. These are similar to the cellular broadcast towers used for broadcasting by the network providers, but are much smaller, usually intended for use in one building. Modern cellular repeater amplifiers can rebroadcast cellular signals inside a building. The systems usually use an external, directional antenna to collect the best cellular signal, which is then transmitted to an amplifier unit which amplifies the signal, and retransmits it locally, providing significantly improved signal strength. The more advanced models often also allow multiple cell phones to use the same repeater at the same time, so are suitable for commercial as well as home use.
