Advantages And Disadvantages Of Analog Signal Processing

There is a clear difference in image quality between digital and 35mm film. The quality of films can be measured in different ways, such as the resolution of the picture, the noise and grain of

ABSTRACT- An Artificial Neural Network (ANN) is an information processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information [1]. Artificial Neural Networks (ANN) also called neuro-computing, or parallel distributed processing (PDP), provide an alternative approach to be applied to problems where the algorithmic and symbolic approaches are not well suited. The objective of the neural network is to transform the inputs into meaningful outputs. There are many researches which show that brain store information as pattern. Some of these patterns are very complicated and allows us to recognize from different angles. This paper gives a review of the artificial neural network and analyses the techniques in terms of performance.

Nowadays, students are grounded by the advancement of technology. Facebook, WhatsApp, Twitter, and other digital devices occupy their leisure time (Bergmann and Sams 20). In the conventional class, students are not permitted to use it. If the millennial’s teachers still use traditional method, it will only aggravate teacher-student relationship (Bergmann and Sams 20). On the contrary, flipped educators infiltrated electronic equipment instead of conflicting it. With reference to the research conducted by Raul Burial in the States, the feedback of using videos from 1,200 participants was overwhelmingly positive. It acknowledged that students had great comfort with using technology while learning and revealed that instructional video was a powerful tool for content delivery and drawing students’ attention (Mathewson). Moreover, Keller and Share at UCLA have concluded in their research that it was imperative and relevant for students, regardless of background or circumstances, to have basic media literacy in order to be prepared for the demands of life that they may confront on a

The basic concept of the Digital Logic Families are needed to be understand first. Fan in, Fan out, Noise Margin, Propagation Delay, Voltage Threshold and Wire Delay are basic concepts out of which Fan out and Noise Margin is explained below.

Digital and microcomputer applications, telecommunications, image processing, digital signal processing, computer architecture, electromagnetic compatibility and computer insights are some involved in the recent progresses in computer engineering. These fields

A filter is a designed circuit which act to pass signals with desired frequencies and reject or attenuate others. If the filter consists of passive element that are resistor (R), inductor (L) and capacitor (C), it is called as passive filter. Meanwhile, active filter consists of active elements such as transistors and op amps alongside the resistor (R), inductor

Filters can either emphasize or reduce some frequencies from a signal. There are different types of filters that can be used. There are different types of filters that can be used. There are also filters that can reject frequencies within a certain frequency band e.g. band bass or band reject.

Evidence is the collection of information and facts that are used to prove or disprove, test the validity and the truthfulness of theories or beliefs about a certain topic. Evidence is used in everyday situations and is used by everyone and can be categorised in two types of data; qualitative and quantitative. Qualitative data is the use of worded descriptors such as feelings, emotions and beliefs; unlike quantitative data which is the use of numerical and empirical based research and data and is less easily falsifiable. Quantitative data is recorded through specific methodologies that allow for data to be repeated and measured more accurately than that of quantitative date, for example; the use of bar charts allows for a clear understanding of the data being presented, as it uses numerical values which meanings can be understood by all. In comparison, qualitative data, or the recording of feelings or emotions, can be easily interpreted by one person but not so easily by another.

ADC is an electronic circuit which transforms analog signals such as a sound picked by a microphone or light entering a digital camera to digital output, to binary number’s system. DAC does the reverse of ADC. Inputs are binary numbers and outputs are an analog voltage or current signal.

The most important application of the digital image processing is enhancement of the captured image, storage and transmission of the image.

Microprocessor is a semiconductor device which contains most of the central processing unit (CPU) functions and an engine that is fabricated on a single chip (Brain, n.d.). It is a multipurpose and programmable device that process the input data into output results according to instructions stored in its memory which is represented in binary numeral system (Microprocessor, n.d.).

Analog recording does have benefits over digital recording. One was mentioned in the previous paragraph. Analog recordings have a more natural sound. Nothing is taken out of the original recording; it is all there on the record in one natural flow. Another positive of the analog recording is that it is played on a turntable. With the turntable a person can choose among various components that will affect the overall sound. On a CD player a person can not switch the laser to get better sound, but on a turntable a person can upgrade the cartridge. The cartridge holds the needle which tracks the grooves in the record (Day 92). The better the cartridge the better the sound quality. Also, for

Arduino Uno R3 is a microcontroller board. It has 14 digital input/output pins. 6 analogue inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It is much more user friendly to use.

Convolution is a formal mathematical operation relating the input signal, output signal to/from a system and the impulse response of the system.

Anything that conveys the information is signal. Signal can be electrical, optical, sound, etc. All the signals are represented by mathematical functions. Also we can plot the functions(signals).
