The frequency of a ′ (the standard note for tuning musical instruments), for example, could range from a ′ =392 Hz in parts of France to a ′ =465 Hz (Cornet-ton pitch) in parts of Germany. [ 1 ] [ 2 ] Organs were often tuned differently than ensembles, even within the same region or town.
A Pythagorean tuning is technically both a type of just intonation and a zero-comma meantone tuning, in which the frequency ratios of the notes are all derived from the number ratio 3:2. Using this approach for example, the 12 notes of the Western chromatic scale would be tuned to the following ratios: 1:1, 256:243, 9:8, 32:27, 81:64, 4:3, 729: ...
Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.
The way a regular tuner 'hears' and compares the input note to a desired pitch is exactly the same, with no change in accuracy. The least expensive models only detect and display a small number of pitches, often those pitches that are required to tune a given instrument (e.g., E, A, D, G, B, E of standard guitar tuning).

For example, a relatively common arrangement on the bass guitar is to use a detuner on the lowest string to allow the bassist to switch between 'standard tuning' (E A D G) and 'drop D' (D A D G). The latter provides two extra notes (D and D# / Eb) that are particularly useful in several common keys .
Basic automatic frequency control in a radio receiver. У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal.
It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced features, and the ability to tune memory.
