We also provide some theory as it may be handy - below you'll find out how to calculate resonant frequency as well as a short definition about what the resonant frequency actually is. Enter the inductance and capacitance and in no time at all you'll find the resonant and angular frequency. Passive filters are also often accompanied by amplifiers.Ī filter consisting of only one resistor and one capacitor is called a first-order filter.If you would like to calculate the resonant frequency of an LC circuit, look no further - this resonant frequency calculator is the tool for you. Unlike passive low-pass filters, active filters use some gain devices, for example, transistors or operational amplifiers. More complex passive low-pass filters also use inductors.

Only passive components are used in it, therefore it is referred to as a passive low-pass filter. A simple low-pass filter is shown in the picture above. They are necessary for rejecting the high-frequency components of a signal above the Nyquist frequency to satisfy the sampling theorem. Low-pass filters are used for conditioning signals prior to analog-to-digital conversion and are called anti-aliasing filters. They are also used in radio transmitters to block unwanted harmonic emissions. One example is using them in subwoofers to block high frequencies that they cannot reproduce. Such filters are widely used in electronics. The cutoff frequency is determined by the components in the filter circuit. Low-pass filters pass only low-frequency signals and attenuate high-frequency signals. Resistor-capacitor RC circuits can be used as simple low-pass and high-pass filters, integrators, and differentiators. Capacitors are used for energy storage, providing pulse power, for power conditioning, for power factor correction, for AC coupling and DC blocking, in electronic frequency filters, in noise filters, for motor starting, for information storage, in tuned circuits, in various sensing devices, in mobile phone capacitive touch screens, and for many other purposes. You will probably not be able to find an electronic device without at least one capacitor. The time constant of an RC circuit is defined as the time it takes for the capacitor to reach Note that the capacitor will be Capacitors are often used in various electronic and electrical devices and systems. Enter the input values into the boxes, select the units, and click or tap the Calculate button. Note that the voltage is not necessary for the RC circuit time constant calculation. The circuit is connected to a 10 V DC power supply. Example: Calculate the time constant, max.
