What are the advantages and disadvantages of electronics filter?
Electronic filters are used for distinguish the frequency spectrum of EM Wave. it can be high pass filter low pass filter or band pass filter or band stop filter. Advantage are they are higly sensitive to frequency ranges , they amplify the signal partially. and disadvantage is that the value or inductor and capacitor depend on the temperature so effective temperature can cause the change in frequency to passed by that filter.
What is the difference between first order low pass filter and second order low pass filter?
in second order filter attenuation to the frequencies in stop band is higher then first order filters.
What job does a wire do in a circuit?
The wire in a circuit helps to pass power to the electrical appliances.
What does decade means in opamp?
In the op-amp decade means falling down . it is used when we talk about active filter whether it is band pass or low pass or whatever the gain after that (undesired frequency) how falling down is measured in decade for example -20 db decade.
What is the function of the resistor into capacitor?
A RC circuit is a simple filtering circuit. The impedance of R will stay the same across the frequency band. The impedance of C will vary according to 1/jwC (j = i = imaginary number, w = omega/frequency in radians, C = capacitance in Farads). As frequency varies from low frequency to high frequency, an increasingly smaller amount of the signal voltage will "drop" across the capacitor. This is known as a first order (one reactive element, the capacitor) low pass filter if the desired signal is measured across the capacitor. If measured across the resistor, this would be a first order high pass filter. Edit: if you are talking about ESR (equivalent serires resistance), it is a parasitic component inside a capacitor. Theoretically, you don't want it but it's there.
When was High Pass Filter - band - created?
High Pass Filter - band - was created in 1996.
What is a low pass filter?
A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
What happen if you connect capacitor and resistor in parallel in low pass filter?
Only frequencies in the pass band range will be allowed through the circuit. Other frequencies will be attenuated based on the RC values picked.
What does the capacitor in a low pass filter do?
Does not allow high frequencies to pass through the circuit.
What are the applications of filter?
especially it is very much useful in high quality AUDIO applications because of its flat response in both pass band and stop band where as chebyshev will be useful in signal monitoring applications where the phase is not important criterialow pass filters are used to filter noise from a circuit .noise is a high freequncy signal, when passed through a low pass filter most of the noise is removed and aclear sound is produced
How parallel and series circuit different?
In a series circuit, current has to pass through each part of the circuit. In a parallel circuit, the current has several alternative paths.
What is the advantage of capacitor filter over inductor filter?
An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter
Why high pass circuit is called as an Differentiator?
That is its function. An RC low pass circuit is an integrator.
What cause a series circuit to work and not work?
A series circuit will work if there is a closed path through which the current can pass, and a voltage source. Otherwise it won't.
What are the applications of Butterworth filters?
especially it is very much useful in high quality AUDIO applications because of its flat response in both pass band and stop band where as chebyshev will be useful in signal monitoring applications where the phase is not important criterialow pass filters are used to filter noise from a circuit .noise is a high freequncy signal, when passed through a low pass filter most of the noise is removed and aclear sound is produced
What is the function of filter in circuit?
Filters are circuits consisting of resistors and capacitors (RC) or inductors and capacitors(LC) to filter unwanted signal components like noise,frequency,etc. Filters can be classified into many types based on different categories. Based on frequency filtering: 1. Low pass(to allow low frequency components) 2.High pass(to allow high frequency components) 3.Band stop or notch (to reject a particular band of frequencies) 4.Band pass(to allow the particular band of frequencies) 5.All pass(to allow all the frequencies)
