In high school, you probably learned that trigonometric functions – like sine, cosine and tangent –can be derived, geometrically, from a circle (hence why trig functions are also known as “circular” ...

The term orthogonality derives from the study of vectors. Most likely you have run across the term in basic trigonometry or calculus. By definition, two vectors in a plane are orthogonal when they are ...

How to measure linearity of an ADC using sine-wave input. How do non-idealities of a sine wave affect ADC linearity while testing it. Testing an ADC’s linearity. To obtain the transfer function of an ...
