Syöttökaappiin

Syöttökaappiin, a Finnish term, translates to "input capture" in English. It refers to a feature or mechanism in electronic devices and software that allows for the precise recording or tracking of input signals. This is particularly relevant in contexts such as digital signal processing, microcontrollers, and audio/video equipment.

The primary function of input capture is to detect and record the exact moment an external event occurs, typically represented by a change in a digital signal. This can be a rising or falling edge of a pulse, a specific voltage level, or any other predefined condition. When such an event is detected, the system captures the current value of a counter or timer. This captured time value provides a precise timestamp for the event, enabling accurate measurement of frequency, pulse width, or other timing-related characteristics of the input signal.

In microcontrollers, input capture modules are commonly used for tasks like interfacing with encoders, measuring the speed of motors, or decoding signals from sensors. In audio and video systems, input capture might refer to the process of digitizing analog audio or video signals for recording or processing. The term emphasizes the act of "capturing" the input data at a specific, often critical, point in time, distinguishing it from continuous data streaming. The accuracy and timing precision offered by input capture mechanisms are crucial for many real-time applications.
