Swept sine waves, white random noise, and the Dirac impulse function all provide flat responses and all are available in arbitrary waveform generators. But this cannot happen forever because, every time the capacitor or inductor charges and discharges some energy (voltage) is lost due to the resistance of the wire or as magnetic energy and slowly the magnitude of the resonance frequency would fade away as show in the below waveform. I also tried it with few other known inductor values and they are seemed to work just fine. The best answers are voted up and rise to the top, Not the answer you're looking for? The subtraction removes the notch at the low-frequency end of the spectrum. Connect and share knowledge within a single location that is structured and easy to search. As you can see the magnitude of the signal dies away as time increases so we can select any one complete cycle of the signal. I measure the resonant frequency of a speaker by using a series resistor (maybe 100 ohms) from my amplified signal generator and listen for the peak output from the speaker or see it on my oscilloscope. His approach is simple: Monitor a function generator with an oscilloscope, but put the crystal under test in series. Then you can multiply the number of horizontal divisions by the time/division to find the signals period. process and showcase important trade-off decisions. It used to be any good electronics experimenter had a bag full of crystals because you never knew what frequency you might need.. A tank circuit is circuit in which we will have an inductor and capacitor connected in parallel to each other and when the circuit is powered the voltage and current across it will resonant at a frequency called resonating frequency. Tektronix designs and manufactures test and measurement solutions to break through the walls of complexity, and accelerate global innovation.
