What is need of scaling in digital signal processing?

saturation arithmetic eliminates limit cycle due to overflow, but it causes undesirable signal distortion due to the non linearity of the clipper.In order to limit the amount (MORE)

How do you convert digital signal to analog signal?

There are quite a few ways to build a digital-to-analog converter  (DAC or D/A). One of the more common circuits is the "R/2R"  resistor ladder. It gets its name from its cl (MORE)

What is digital signal and how its different then analog signals?

Digital signals have discrete encoded states that they switch between. They can only assume the defined encoded values. Errors can often be easily detected and sometimes corre (MORE)

What are advantages and disadvantages of digital signal processing?

Adv. Digital · easy to store and use, that is why computers use it. · Digital data is designed and artificially created, so it is efficient. · Less expensive . DSP (MORE)

How analog signals are different from digital signals?

An analog signal is a signal of varying amplitude. The signal can be: Light of different intensity Light of different colour Varying voltage like that produced by an M (MORE)

What is difference between digital image processing and digital signal processing?

Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Anoth (MORE)

What is the need for convolution in digital signal processing?

  If we need to add two signals in time domain, we perform convolution.   A better way, is to convert the two signals from time domain to frequency domain. This can be (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
