Natural Frequency in Undriven OscillatorsĪlthough we can quantify a natural frequency in mechanical and electrical harmonic oscillators, the system never really oscillates at the natural frequency. natural frequency in purely linear oscillator circuits. Let’s clear up the difference between the resonant frequency vs. Things become mathematically confusing for some designers in that the real response of an oscillator is defined in terms of three different frequencies.
Just like mechanical oscillators, oscillator circuits can exhibit resonance under the right conditions. In electronics, different circuits will function as oscillators, where the voltage and current exhibit a periodic response in time. Any oscillator has some important physical parameters, and the system’s response when driven will not match the response seen when allowed to oscillator freely. These systems are conceptually simple, but their mathematical models fail to account for realistic properties in these systems. Those familiar with oscillators are most likely to think in terms of a simple harmonic oscillator, like a pendulum or a mass on a spring.
