| | Digital signal processing - Wikipedia, the free encyclopedia |
 | | In order to use an analog signal on a computer it must be digitized with an analog to digital converter (ADC). | | | The output of an FIR filter to any given input may be calculated by convolving the input signal with the impulse response. | | | With the increasing use of computers the usage and need of digital signal processing has increased. |

| | Introduction to Digital Signal Processing |
| | The development of digital signal processing dates from the 1960's with the use of mainframe digital computers for number-crunching applications such as the Fast Fourier Transform (FFT), which allows the frequency spectrum of a signal to be computed rapidly. | | | This generates a digital output as a stream of binary numbers whose values represent the electrical voltage input to the device at each sampling instant. | | | The processing of a digital signal is done by performing numerical calculations. |

| | Digital Recording Techniques |
| | The difference between the instantaneous analog signal and de digital representation is digital error. | | | The computers may be common microcomputers as well as main-frame computers. | | | In the simplest case, the word digital refers to the representation of a quantity in numerical form and analog refers to a continuous physical quantity. |

| | FDI DSP - Digital Signal Processing - Design Guide |
| | A digital filter computes a quantized time-domain representation of the convolution of the sampled input time function and a representation of the weighting function of the filter. | | | Simply said, the digitized input signal is mathematically influenced by the DSP program. | | | Instead of using a commercial DSP with software algorithms, a digital hardware filter can also be constructed from logic elements such as registers and gates, or an integrated hardware block such as an FPGA (Field Programmable Gate Array). |

| | DNA-Based Digital Signal Processing |
| | Although, using DNA to optimally solve the disparity estimation problem is currently impractical we observed that matching of digital signals is a fundamental problem that arises in many signal-processing applications. | | | As stated previously, one of the key characteristics of the digital signal-matching problem, is the fact that the matches are typically imprecise, due to the nature of the problem (e.g., photographs of the same scene from different perspectives or with different lighting conditions) or the presence of noise in the data. | | | In digital databases the query time increases proportionally to an increase in the size of the database. |

| | All data that a computer processes must be encoded digitally, as a series of zeroes and ones. | | | Although digital representations are approximations of analog events, they are useful because they are relatively easy to store and manipulate electronically. | | | Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on. |
