sähkösignaaleja
Sähkösignaaleja, or electrical signals, are variations in electrical current or voltage that convey information. They are fundamental to the operation of electronic devices and communication systems. Electrical signals can be analog or digital. Analog signals are continuous and can represent a wide range of values, such as sound waves in a microphone or voltage levels in a sensor. Digital signals, on the other hand, are discrete and represent binary information, either 0 or 1, as in the case of data transmission in computers.
Electrical signals are generated by various sources, including sensors, microphones, and transmitters. They are transmitted through
Electrical signals are processed and interpreted by receivers, amplifiers, and other electronic components. They are used
