Comparison Philips AJ-3123 vs Philips AJ-3115

A type of tuner used in radio receivers.

- Analogue. Tuning to the desired frequency in such tuners is carried out using the wheel. This scheme is considered more convenient than digital trim (see below), but the accuracy of analogue regulators is lower. This can make it difficult to use the receiver with numerous stations in a small frequency range (especially for FM broadcasts in large cities). In addition, the analogue tuner "does not know how" to memorize stations.

- Digital. The direct tuning of the tuner in such receivers is performed by an electronic circuit; the user only sets the desired frequency using the increase / decrease buttons or, in advanced models, from the numeric keypad. These tuners are somewhat less convenient for manual tuning, but they do a good job of fine tuning. Also, many receivers with digital tuners have the function of storing stations (see "Station Memory"), automatically searching for all available stations, etc.
