Its function is to process the waveform or frequency of the input signal by using the characteristics of the discrete time system. Or, the input signal is transformed into a certain output signal to achieve the purpose of changing the spectrum of the signal. Digital filter can be realized by two methods: one method is to use digital hardware components into a specialized device, this device is called a digital signal processor; another method is the direct use of the computer, the required operation program allows GM computer to complete, which is realized by computer software. low pass filter Low pass filter is a circuit that can pass low-frequency signal and not pass high and high frequency signal in vehicle power amplifier, and its function is to filter the middle and high pitch components of audio signal, and enhance the bass component to drive the loudspeaker's bass unit. Most of the vehicle power amplifiers are all band power amplifiers. The AB class amplification design is usually used, and the power loss is relatively large. Therefore, it is the best choice to save the power and ensure the quality of sound. In addition, high pass filters often appear in pairs with low pass filters, either of them, in order to send a certain sound frequency to the unit where it is supposed to go. A low pass filter is an electronic filter that allows a signal below the cut-off frequency to pass through, but the signal that is higher than the cut-off frequency can not be passed. Bandpass filter An ideal filter should have a completely flat passband, for example, there is no gain or attenuation in the passband, and all frequencies are completely attenuated outside the pass band. Besides, the pass band transformation is done in a very small frequency range. In fact, there is no ideal bandpass filter. The filter is not able to completely attenuate all frequencies outside the desired frequency range, especially in the range of the desired passband, which is also attenuated but not isolated. This is usually called the roll drop phenomenon of the filter and is represented by the attenuation range of dB per ten octave. Usually, the filter is designed to ensure that the roll down range is narrower and better, so that the performance of the filter is closer to the design. However, as the rolling range becomes smaller and smaller, the passband becomes no longer flat - the "ripple" begins. This phenomenon is especially obvious at the edge of the passband, which is called the Gibbs phenomenon. Analog filter The analog filter is a common transformation device in the test system or the special instrument. For example: bandpass filter used as frequency selection device in spectrum analyzer; low pass filter used in digital signal analysis system of the anti aliasing filter; highpass filter is used to eliminate the interference of low frequency acoustic emission detector noise; bandstop filter notch filter used in eddy current vibration meter, etc.. The bandpass filter used in the spectrum analysis device can be divided into two kinds according to the numerical relationship between the center frequency and the bandwidth. One is that the bandwidth B does not change with the center frequency. It is called a constant band broadband pass filter. When the center frequency is in any frequency band, the bandwidth is the same. The other is that the ratio of the bandwidth B to the central frequency is constant, which is called the constant bandwidth ratio band pass filter, and the higher the center frequency is, the wider the bandwidth is. Surface acoustic wave filter Surface acoustic wave refers to the propagation of sound waves on the surface of an elastic body, which is called an elastic surface wave. The velocity of the surface acoustic wave is about 100 thousand times smaller than that of the electromagnetic wave. Surface acoustic wave filter is a piezoelectric ceramic material, the quartz crystal pressure, a special device which is used to filter the piezoelectric effect and acoustic wave propagation properties, are widely used in TV and video frequency circuit, to replace the LC filter, so that the quality of image and sound is greatly improved. Dielectric filter Dielectric filters consist of low loss, high dielectric constant, frequency temperature coefficient and thermal expansion coefficient of dielectric ceramics, and can withstand high power. Its characteristic is the low insertion loss and high power efficiency, bandwidth, especially for CT1, CT2900MHz, 1.8GHz, 2.4GHz, 5.8GHz, mobile , car , wireless headset, wireless micro, wireless radio, cordless and integrated transceiver diplexer etc. to coupling filter. Active power filter Active power filter is a new power electronic device harmonic and reactive compensation, harmonic it can change the frequency and size and reactive power compensation can make up for the shortcomings of the passive filters, obtained better than passive filter compensation characteristics, is an ideal device for harmonic compensation. As early as 70s, the basic principle and the main circuit topology of the active power filter have been determined, but due to the technical constraints at that time, the active power filter can not be implemented. After entering the 80s, the emergence of new power electronic devices, the development of PWM control technology and the theory of instantaneous reactive power greatly promoted the development of active power filter technology. The active power filter has been widely used in industrial and civilian devices abroad, and the capacity of the single unit has been gradually improved. Its application area is developing from the compensation of the user's own harmonics to the improvement of the power quality of the whole power system.
