Question

If we give two signals to ideal frequency detector what is the output

Answer 1

If we give two signals to ideal frequency detector the output is 0.1 kHz sinusoid.  

Sinusoid is “a curve representing periodic oscillations of constant amplitude as given by a sine function.”  

Properties of the Ideal Frequency detector are High detection efficiency; count photons; register arrival time etc.,  

 Hope this helps you.
