It must be an analog filter. The high frequencies must be attenuated before any digital sampling takes place, to ensure that these high frequencies are not sampled as false signals. See the related link.

How can the anti-aliasing filter removal be achieved in digital image processing?

In digital image processing, the removal of anti-aliasing filter can be achieved by applying a process called deconvolution. This process involves reversing the blurring effect caused by the anti-aliasing filter to enhance the sharpness and clarity of the image.


What is the function of an anti aliasing device?

An anti aliasing device uses the technique of minimizing distortion when presenting a high-resolution image at a lower worst quality image. Anti aliasing devices are often used in photography, computer graphics and digital audio among other things.


What is anti-alias filter?

From the Vibration Analysis Dictionary (www.vibronurse.com): Aliasing - A phenomenon which can occur whenever a signal is not sampled at greater than twice the maximum frequency component, causing high frequency signals to appear at low frequencies. Aliasing is avoided by filtering out signals greater than half the sample rate. Anti-aliasing filter - A low-pass filter designed to filter out frequencies higher than 1/2 the sample rate in order to prevent aliasing.


How can you overcome the aliasing effect?

To overcome the aliasing effect, you can increase the sampling rate or use an anti-aliasing filter before sampling the signal. Additionally, you can employ oversampling techniques or apply signal processing algorithms like interpolation or filtering to reduce or eliminate aliasing artifacts in the signal.

What is 4xAA?

4 x (anti-aliasing)


Why can you not get the anti-aliasing in the Crysis demo to work you put anti-aliasing on 4X and when you get out of the menu and go back it's off?

Because its a shortcut to the advanced settings. Next time, set the Shaders to Low, then switch on the Anti Aliasing. Then apply and go back to the options. You'll see that the AA is back on off, but the advanbce options, Shaders is on High. So it does work.


What does anti aliasing mean?

anti aliasing (AA) is the process of smoothing edges so they dont appear jagged. The number associated with it (2x, 4x, 8x, 16x, 32x) is the number of samples taken to smooth it. to make it appear smoother, pixels around an area are added together then an average color is found. basically, the higher the number, the smoother it will appear. however, AA is some of the most taxing work that a CPU/GPU will do and can quickly overwhelm it the wikipedia article here shows very good examples of the different levels of anti aliasing http://en.wikipedia.org/wiki/Anti-aliasing


What are numerical relays?

As we know numerical relays use DIGITAL SIGNAL PROCESSOR as its computational hardware and based on microprocessor. WORKING: Analog input is feed into the anti aliasing filter which is a low pass filter.Output of this filter is feed into the sample and hold circuit , frequency of sampling should be twice of our highest frequency of interest(according to the nyquist criterion).if sampling frequency kept low than aliasing input may occur. after the sampling, signal are feed into the multiplexer,where all the signal get multiplexed and we have a single signal.this signal is feed into the analog to digital converter.this digital signal is feed into the microprocessor and microprocessor generates control signal according to its input. for example if you are using N.R. for over-current protection than you should set a value of current in your program.if the value of current passes through the circuit is greater than the set value..than N.R. enables the circuit breaker and hence our system is protected..
