Once the compilation is complete, the next step is testing the source code by clicking on Load. The LED Turns off. The turning off of the LED means the program has been loaded. As Pin 7 remains off, the launch pad turns pin 3 on and off, while there is no connection to it. The next step is to create a connection to pin 3 using a wire connection. Once the new program is loaded, the LEDs are wired correctly to the pins. The seven LEDs all begin to blink one at a time. The blinking pattern runs repeatedly. The result is shown in the figure below. This improves the cycle resolution for the higher resolution PWM. The second modification was to reduce the low PWM carrier frequency of the undesired harmonics. The initial harmonic now starts from 40 kHz instead of 50 kHz, making more of the harmonic go in to the analog low-pass filter and increases the ripples of the harmonics. The filtered PWM performs as a DAC converter in line with the selected analog low-pass filter (Osborne, 1980). The filtering process uses active filters instead of passive filters. In spite of the active filters being able to avoid issues of impedance loading, passive filters minimize the cost and complexity. The filtering releases analog signal out of digital signals as demonstrated in figure 8 below. The code written in Energia launch pad experienced a challenge of incompatibility of the operating system. Initially, the operating system did not have the connection to the hardware (Heath, 2003). It displayed an error message “No unused FET found”. This was a great risk as it meant that the code cannot execute until it is connected to the LED lighting system. This demanded a configuration of the LED display system to the computer as an interface. The configuration is a risk considering the conflict between the launch pad and other hardware components that require the computer. The Energia Launch pad gives a conversion from analog to digital to generate a digital value.
In the paper “Logic and Programming: Ripple Generator” the author analyzes the frequency range used in the generation of the PWM signal, which is between 0 and 255, with an interval of 50 between each frequency and when the input is read as the correct key…
The aim of the paper is to develop an application that given a set of patient constraints will produce a hospital schedule that will try to satisfy the patient’s needs. Some of the needs a patient might require:
- Patient only available at certain hours
- Patient only available at certain days
- Patient may need to attend hospital roomes at the same time with his brother or sister
The various programming languages available for computer programming are classified according to the paradigm in which they operate. Each programming paradigm is different in style, concept and methodology from others. Different paradigms are suitable for different purposes egg – object oriented paradigm considers any program written as a collection of various objects that interact with each other, database programming paradigm is ideal if the program is intended to handle large amount of data and logic and constraint based programming is the most suited for search problems.
In this scenario, the instructions are given to the computer to carry out a specific task. In addition, these instructions are provided to the computer according to the rules of the programming language. At the present, there are numerous programming languages, which can be used to develop a wide variety of software applications (Shelly et al., 2005; Norton, 2001).
The author explains that the full-wave with center-tapped transformer has two diodes acting as half-wave rectifiers and whose negative ends are connected to the two terminals of the transformer secondary. The two diodes provide a full-wave output. The DC currents of the two half-wave rectifier diodes are equal and opposite.
As the computer science is an evolving and dynamic discipline, therefore, it is difficult to categorize the already developed computer languages. Some of the authors have classified the computer languages into three (3) categories include: machine level language, assembly level language and high level language (Venit and Drake, 2010).
Though every language is built on the common ground of communicating “Efficiently and Effectively” with the machine, each language has its own merits and demerits. Some were developed with a specific purpose, some with a specific business application, some for scientific purposes, and some to overcome the demerits of other languages.
The author states that Python programming language was created by Guido van Rossum and this development was supported and encouraged by various other programming paradigms such as by ABC, Haskell, Java, LIST programming, Icon and Perl programming languages. In python, programs are written using an indentation technique.
Object programming on the other hand refers to a programming technique that is founded on the aspects of data structures which imbibe the data (Hughes, 2009). It is important to note and record that the data exist in
