AboutAbout the lab
Measuring electrical signals to clarify how they work
The Yoshida Lab studies electrical signals that change from moment to moment in everyday environments, such as audio signals, electrostatic discharge currents, and electromagnetic noise.
The lab senses (measures) and analyzes these signals to clarify the factors and mechanisms by which they affect electronic devices.
It also pursues electronic circuits and signal processing methods that reduce these effects and improve performance, from both the hardware and software sides.
The research fields listed include acoustic and image information processing, biometric security, transient signal analysis, electrostatic discharge (ESD), and electromagnetic compatibility (EMC).
Key terms
- Electrostatic discharge (ESD)
- A phenomenon in which electricity flows all at once between charged objects. It is a factor that can affect electronic devices
- Electromagnetic compatibility (EMC)
- The ability of electronic devices to operate without being disrupted by electromagnetic noise and without disrupting their surroundings
- Biometrics
- Technology that verifies a person's identity using physical characteristics such as fingerprints or faces
