High-pass filters are often used in the biomedical world for image processing, control systems, and filtering out of DC signals in measurements as well as…
In an electrical circuit, it may be useful to have a circuit component with adjustable properties. A potentiometer is just that! Because a potentiometer allows…
In an electrical circuit, it may be useful to have a circuit component that can detect changes in light intensity. A photodetector provides a user…
In an electrical circuit, the input voltage supplied from a voltage source may not fit the requirements of a circuit component. The use of voltage…
Many electrical biological signals are relatively low frequency. Outside sources of noise, such as that from the power grid and patient movement, can have higher…
Electrical signals from biomedical devices are often small in amplitude and can be easily distorted by noise sources, the most common of which comes from…
Infrared (IR) sensors can detect and/or emit infrared radiation in order to sense objects in a wide variety of applications. IR sensors have a number…
