- An oscillator with a natural frequency of 380 Hz is driven by a 790 Hz sinusoidal signal. At what frequency does it oscillate?Please help thank youIn determining which has the longer period, an oscillator with a frequency of 200 Hz or one with f = 300 Hz, can the subject matter expert help me to review, the difference between ...1/2 and 1/3? The likely answer is 200 Hz, the idea that the smaller the denominator, the longer the period. Just guessing.
