Question

An oscilloscope is basically designed to convert _________ .

• A. visual signals to electrical signals
• B. sound signals to electrical signals
• C. electrical signals to visual signals
• D. sound signals to visual signals

Answer 1

The correct option is C electrical signals to visual signals

C

The main purpose of an oscilloscope is to graph an electrical signal as it varies over time. Most scopes produce a two dimensional graph with time on the x-axis and voltage on the y-axis. This is also useful for measuring such things as clock frequencies, duty cycle of pulse-width-modulated signals, propagation delay or signal rise and fall times.
