The capacitor is a reactive component used in analog electronic filters due to the function of the capacitor’s impedance frequency. Depending on the frequency of the capacitor that affects the signal. This property is therefore widely used in the design of filters.
The circuit diagram of the filter capacitor is shown below. In this circuit, the capacitor works like a high pass filter that allows high frequencies and blocks direct current. Similarly, they can also work as a low pass filte r to allow DC and block AC. Here the capacitor is connected in parallel with the component instead of connecting in series.
The capacitor can affect the signal depending on the frequency. Therefore this property is widely used in the design of filters. An analog electronic filter such as LPF can be used to perform the function of predefined signal processing. The main function of the filter capacitor is to allow low frequency and block high frequency.
In a power supply, a capacitor is used to filter the pulsating DC o/p once rectification so that an almost stable DC voltage can be supplied to the load. 3). What are the limitations of the capacitor filter?
The capacitor used to filter a specific frequency is called a filter capacitor, which is a series of frequencies in the electronic circuit. Typically, a capacitor filters low-frequency signals. The frequency value of these signals is close to 0 Hz, also called DC signals. This capacitor is therefore used to filter out unwanted frequencies.
Generally, a capacitor filters out the signals which have a low frequency. The frequency value of these signals is near to 0Hz, these are also known as DC signals. So this capacitor is used to filter unwanted frequencies.
