Respuesta :
The right answer for the question that is being asked and shown above is that: "c. diode signals." Electronic signals that are smoothly varying signals produced by continuously changing the voltage or current in a circuit are diode signals.
Answer: The correct answer is "analog signals".
Explanation:
Digital signal: This signal varies as 0 or 1. It is discrete signal.
Cathode rays: They are the streams of the negatively charged particles.
Diode signals: Diode is a semiconductor device. It changes the alternating signal to the direct signal.
Analog signals: In this signal, the signal is varying by continuously changing the direction voltage or current with time. It is a continuously varying signal.
In the given problem, electronic signals that are varying signals produced by continuously changing the voltage or current in a circuit are analog signals.
Therefore, the correct option is (d).
