Global Analog Filters Market: Introduction
Analog filters are basically networks which process signals in a frequency dependent manner. Analog filters are considered as a basic building block of signal processing and are used in electronics. The analog filters separate the audio signals from distortion and other noise signals before applying audio signals to the loud speakers. Thus the analog filters isolate the desired signals from unwanted noise signals or interference. Analog filters operates on continuous time signals. In others terms analog filters are just limiting case of digital filters as the sampling rate is allowed to go to infinity.
Low pass analog filters are used to stabilize amplifiers by rolling off the gain where excessive phase shift can cause oscillations. High pass analog filters are used to block DC offset in the single supply circuits or high gain amplifiers. Ideal analog filters have an amplitude response at a fixed gain that is unity for frequencies of interest and everywhere else the amplitude will be zero. Unfortunately, the ideal analog filters cannot be easily built, as the transition from stop band to pass band cannot be instantaneous. The low pass analog filters pass low frequency, by blocking high frequency signals and high pass analog filters pass high frequency by blocking low frequency signals. Whereas band pass filters pass only signals between two given frequencies, blocking higher and lower frequencies.
Global Analog Filters Market: Dynamics
It is very easy to apply analog filters as there is no need to use the microprocessor, thus the ease of use is one of the major factors driving the growth of the analog filters market. While manufacturing analog filters very few components are needed, thus it is also one of the factor fueling the growth of the analog filters market. Another factor contributing to the growth of the analog filters market is that there is no need to write any programs or algorithms.

However the analog filters are very sensitive to the environmental changes due to the tolerance of the components used for its manufacturing. Thus the highly sensitive nature of the analog filters is one of the major factors restraining the growth of the analog filters market. Also the analog filters are costly as compared to that of the digital filters, thus high cost is another factor hindering the growth of the analog filters market.
