Abstract: A new signal subspace approach for estimating the frequency of a single complex tone in additive white noise is proposed in this correspondence. Our main ideas are to use a matrix without ...

This letter proposes an improved dc-single tone approximation model to calculate the RF-dc conversion efficiency, voltage sensitivity, and input impedance of rectification circuits comprising n diodes ...

Using nuclear magnetic resonance, researchers at ETH Zurich have studied the atomic environments of single platinum atoms in ...

There's a phenomenon of human hearing known as binaural beats. It occurs when two pure tones of different frequencies are ...

A frequency distribution is a table or graph that shows how often values occur within specific intervals. It is commonly used in statistics to analyze quantitative data, such as census results or ...
