High Frequncy System Laboratory

Did you know digital signal processing involves the addition and multiplication of “0s” and “1s”?

Radio waves are one of the representative high frequency electrical signals that are used in TVs and mobile phones to enrich our lives. Our laboratory is studying wireless communication systems using radio waves. More specifically, we are inputting data we want to send into radio waves and obtaining data from received radio waves through the process of adding and multiplying “0s” and “1s.”

Study Fields

For Society

High frequency signals are used in the field, in which images and voices are converted into digital signals such as in terrestrial broadcasting, mobile phones and amateur radio. They have become a key technology to allow air conditioners, washing machines and other latest home appliances to make complicated “judgments.”
