Hello all,
Simple question (DSP stuff).
What frequency is this:-
10sin(4200piet)
-8.16Hz? No!

Assuming it is v(t)= 10*sin(4200 * pi * t)..
It is a 10 volt peak (20 V P-P) sine
that is at 2100 Hz. In this case,
the angle is in radians, and 2 * Pi
radians is one cycle (360 degrees).

or maybe it's v(t)=10*sin(4200*pi*(e^t))
or v(t)=10*sin(4200*pi*e*t)
