Signal Transduction


Signal Transduction

The Drum Device is generated in a way that a sound signal is produced as the final output from analogue electrical signals which have being transducted from the three sensors,Touch/Pressure,Accelaration and Gesture.

The touch or pressure sensors are present on the surface of the drum head or batter part and they sense the specific area to which the force is applied.Depending on different areas where the force is applied,the signals produced are transducted into analogue electrical signals with relavant to each area.

The acceleration sensors possess sensing components which are sensitive to the speed of the hand movements.They detect the speed and then convert it into analogue electrical signals.

The gesture sensors with specific sensing componebrs detect at what planes that the hand/fingers hit the drum head and then again convert it into an analogue electrical signal.

Finally all these analogue electrical signals produced from the three sensors,touch/pressure,acceleration and gesture are obtained and their summation is converted in to a sound signal after being sending through an  actuator and finally emitted trough the speakers.

In this way,the drum detects which sound should be produced when a specific area of the drum head is touched with a specific speed of the hands and specific gesture.

Introduction Of Drum (Learning tool)

Article 01                                                             Introduction of Drum Gata beraya known as Kandyan Bera traditionally been used in the Kandyan (up country) dance. Figure 1 show parts of the drum. 1    Urapota 2    Kapumhama 3    Bera Kanda 4    Wam Asa 5    Dakunu Asa 6    Kanwaraya 7    Weniwara Karalla 8    Warapata There are two sides of the drum called Wam asa and Dakunu asa . Right side ( Dakuny asa ) of the drum is covered with the skin of a Monkey while the opening on the other side ( Wam asa ) is covered with a  Cattle skin. For this reason, there are different sounds from each other. Figure 2  shows one side of the drum. ...

Signal Processing - Nyquist Sampling Theorem

Image
Nyquist Sampling Theorem A continuous time signal can be represented in its samples and can be recovered back when sampling frequency f s  is greater than or equal to the twice the highest frequency component of message signal. fs ≥2 fm The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals. For analog-to-digital conversion (A DC ) slices, called  samples , of the analog w aveform  must be taken frequently. The number of samples per second is called the sampling rate or sampling frequency. As tube amplifiers give a more pleasant mutation and compression to musical signals than transistors, analog tape similarly warms up and fattens the sound. Though, it is not needed to refrain from the other different uses of it. Other techniques such as tube compressors, to fatten the sound if needed.  there is no such thing as the  perfect ...

Article 05 Learning Tool For Piano, Steel Drum, And Harp Over the past century, there have been many advances in the music industry and in educational practices. This article is based on the piano, the steel drum and the harp created by Politehnica University of Bucharest (PUB), Romania. This is a software tool which allows the users to play a virtual instrument and afterward to listen to their own progress. The application was developed using  Java technology. The main screen of the application is available in figure 1. This application is designed just as straightforward. Figure 1 Figure 2 Figure 2 there are two playing modes.User interfaces of two instruments. The application provides insight information about each available virtual instrument, as seen in Figure. 3.. Two languages have been used. English and French. So the user can be easily used. The beginner can easily and accurately learn everything. Figure 3 Reference ...
