Which frequency range are synchros designed to operate on?

Synchros are electromechanical devices used for transmitting information about angular position. They function by converting angular movement into electrical signals and vice versa. The standard frequency range for synchros, particularly in their applications such as in aircraft and maritime systems, is typically within the range of 60 to 400 Hz. This frequency range ensures reliable and accurate performance in the environments where synchros are deployed, which often involve varying load conditions and the need for consistent signal integrity.

Operating within this frequency range allows synchros to maintain their characteristic response times and accuracy, essential for tasks such as navigational and attitude sensing. Higher frequencies may not be necessary and could complicate the design without providing significant benefits, while lower frequencies would not meet the operational requirements of most synchro applications. Thus, the choice of 60 to 400 Hz aligns perfectly with the operational parameters for synchros, making it the correct answer.
