Generate a 1kHz Pulse to Generate a Pure Sine Wave with combined Resistor, Inductor, Capacitor (RLC) circuit.
f = 1/ [ 2π sqrt(LC) ]
L = 1/ [ 2π x √C x f] ²
C = 1/ [ 2π x √L x f] ²
L- Henry
C-Farad
f- Frequency
The frequency of oscillation is determined by combination
of inductor and capacitor using the formula above.
What does the resistor do?
Resistor shapes the wave into a nice sine wave.
The higher the value of a resistor, shapes a nice sine wave form, but too high reduce the amplitude of the wave. A low value resistor, distort the waveform and too low makes the waveform more like a Square Wave.
The correct frequency produce a constant amplitude sinewave for a given inductor and capacitor value.
