Swept sine waves are useful when you want to test a product over a wide frequency range. A large research project included the requirement to determine wave propagation in the open ocean. This ...

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” ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...

The vernal equinox is fast approaching and you may have noticed that the days are getting longer. Well, they've been getting longer since late December, but the rate at which it's happening seems to ...

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 ...

Optical or magnetic sensors for position and angle sensing in motion control systems generally provide sine and cosine signals for conversion. The 90° phase shift between sine and cosine allows ...

CBSE 2024-25 Competency-Based Questions With Answers: The Central Board of Secondary Education (CBSE) has increased the weightage of competency-based questions to 50%. Thus, students must prepare to ...

You might have already passed that silly course with a title something like "Introductory Algebra and Trigonometry." It covered a bunch of stuff, but the important part was that the class was a ...
