Low pass filter for Subwoofers
In the form it appears the theoretical circuit of filter. In first glance we see three different circuits that are mainly manufactured round two operational amplifiers. This circuits constitute mixed, amplifier with variable aid and a variable filter. The manufacture end needs a circuit of catering with operational tendency of catering equal with ±12. the operational amplifiers that constitute the active elements for this circuits of are double operational type as the TL082 and NE5532. The operational these amplifiers belong in a family provided with transistor of effect of field IFET in their entries. Each member of family allocates in their circuit bipolar transistor and effect of field. This circuits can function in his high tendency, because that they use transistor of high tendency. Also they have high honor of rhythm of elevation (slew rate), low current of polarization for the entries and are influenced little by the temperature. The operational these amplifiers have breadth of area unity gain bandwidth 3MHz. A other important element for their choice is the big reject of noise, when this exists in the line of catering.
The price of reject is bigger than 80dB, their consumption is small, from 11 until 3 mA. They are internally sold in nutshell with eight pins and allocate two operational amplifiers, In the same line in nutshell 14 pins they incorporate four operational, In the trade they are sold with code TL074, TL084 and TL064, In nutshell with eight pins they are sold operational amplifiers TL061 TL071 kajTL081. In the manufacture we used the TL082 that has two operational. First operational from the TL082 it works as amplifier and mixed for the two channels, In his negative entry he exists one small mixed with two resistances. A potentiometer in this rung determines the aid of circuit. In the point this left winger and the right channel of preamplifier they are added means of two resistances. En continuity the operational strengthens signal with aid made dependent from the price that has the potentiometer.
The place of runner is proportional with the aid of circuit. The second operational amplifier is the filter of manufacture. The filter of is acoustic frequency of second class and he is made with the materials that are round the operational amplifier. The filter of is low passage with variable frequency of cutting off. This frequency can be altered and take prices from very low frequency the 30Hz or still exceed 150Hz. The frequency of cutting off of filter depends from the prices that have the elements of circuit. Altering the values of elements we can have frequency of cutting off 150Iz, 130Iz, J00Iz, 7Ïz, 6Íz even 3Íz, this prices they can be achieved with the simple rotation of double potentiometer. The circuit of filter has been made around one operational' that it has completed TL082 that is double operational amplifier. In the exit of filter we will link the plug of expense where is connected the amplifier. In the exit of circuit is presented, the limited as for the breadth of frequencies, signal that we apply in the entry of circuit. The knownest application they are the filters baxandal for regulating tone low and high frequencies and filters crossover where the acoustic region is separated in subareas, in order to it leads the corresponding loudspeakers. The application that to you we propose is a simple filter of region that limits the acoustic region (20-20000Hz) in the region 20-100Hz.
The described circuit features a theoretical filter design that incorporates two operational amplifiers, specifically the TL082 and NE5532, which are double operational amplifiers. The circuit is designed to operate on a dual power supply of ±12V, making it suitable for a variety of audio applications. The operational amplifiers selected for this design are characterized by their high slew rate, low input bias current, and minimal temperature drift, which enhance performance in audio signal processing.
The first operational amplifier in the TL082 configuration acts as a mixed amplifier, handling two audio channels. It is configured with a negative feedback loop that includes a potentiometer, allowing for adjustable gain. This gain setting is crucial for tailoring the circuit's amplification to the input signal levels. The second operational amplifier serves as a low-pass filter, designed to attenuate frequencies above a specified cutoff frequency, which can be adjusted through the use of a dual potentiometer. The filter design is a second-order low-pass filter, enabling flexible cutoff frequency adjustments ranging from 30Hz to over 150Hz, depending on the circuit component values.
The circuit's output connects directly to an audio amplifier, delivering a filtered signal that is limited in frequency response, suitable for applications such as tone control and frequency crossover in audio systems. This filter design is particularly useful in separating frequency bands for different speakers, ensuring optimal sound reproduction across a wide audio spectrum while effectively managing noise and distortion. The implementation of this circuit allows for significant control over audio signal processing, making it a valuable addition to any audio engineering project.In the form it appears the theoretical circuit of filter.
