Wavelength and Frequency

In this experiment, the frequencies are recorded at high certainty values. The increased certainty in these values is due to the high precision of the Amplitude knob. It takes only a few seconds to change the frequency before an effect is seen. When the experiment is repeated for a standing wave with two wavelengths, we get different results. The two-segment waves vibrate with a node at each end and one note in the middle such that the wavelength is equal to the length of the string used in the experiment. The frequency of two segment wavelength is about twice ...

Steel drums or what we called Steel Pan were originally created on the island of Caribbean, Trinidad in year 1930s.However, Steel Pan’s history can be traced back to the confined Africans who were brought to the islands during the 1700s (Steelpan-steeldrums-information.com par. 1). They had taken with them components of their Africa lifestyle such as the enjoying of hand percussion. 2). Hand drums are percussion at Africa called Membranophones. These drums became the main percussion gadgets in the yearly Trinidadian event festivities. In year 1877, the judgment English Government prohibited the playing of percussion in an effort ...

MULTIPLEXERS AND DEMUMULTIPLEXERS

ELEC201 Digital Electronics Partner Name: Objectives The objectives of this lab include: Introduction A multiplexer is a crucial digital circuit that is capable of selecting a single digital signal out of a set or group of signal at its input and passes that signal to its output. It functions as a more as a rotary switch that switches connects one input to the output at a time. On the other hand, the multiplexer does the exact opposite function; it passes multiple digital signal inputs through one of a set or group of outputs. Through multiplexers, several signals can be sent ...

ARITHMETIC CIRCUITS AND COMPARATORS

ELEC201 Digital Electronics Partner Name: Excelsior College Objectives This experiment seeks to: - Examine how addition and subtraction are performed by the use of logic gates. - Examine how binary numbers are compared using logic gates. - Understand the working principle of comparators.

Introduction

It is possible to implement binary arithmetic in hardware through the direct application of basic logic gates. This is through the manipulation of binary numbers using simple gates such as the AND and OR gates, for example, the AND gate can be used to realize a multiplication operation in ...
