Morse first noticed it on the transatlantic telegraph cables transmitting messages using dots and dashes and it has not gone way since. He handled it by just slowing down the transmission. Amplitude Time Figure 8 101101 transmitted data Figure 8 shows a data sequence, 1,0,1,1,0, which wish to be sent. This sequence is in form of square pulses. Square pulses are nice as an abstraction…

Electroencephalogram (EEG) used to measure abnormalities in the brain which related to electrical activity (Fig.1). This measurement tracks and records brain wave patterns by using electrodes are placed on the scalp, and then signals go to a computer to record the results. Abnormal patterns in EEG indicate seizures and other problems [3][6]. The importance reason for using EEG is to diagnose and show seizure disorders. Also EEGs help to help to identify causes of other problems like sleep…

The history of piezoelectricity evolution is over 120 years which was discovered by brothers Curie in 1880. They were Pierre Curie (1859-1906) and Jacques Curie (1855-1941). During the study of the generation surface electrical charge by applying pressure on some material, they found out an unusual phenomenon which was a voltage of opposite polarity was generated by pressure was applied on the crystalline minerals such as quartz. The amplitude of the generated voltage was proportional to the…

variety of instruments depending on whether they create vibrations when being played. They're perfect for percussion, string, and some wind instruments, too. The cello, violin, guitar, or even ukulele can benefit from a pickup that feeds into an amplifier. What's Included Pickup microphone Mounting hardware Battery Myers Pickups The company was started by Gregg Myers, who is currently the CEO, owner, and inventor, but it's also managed by multiple members of his family. This includes his…

Effect processors - Reverb & Delay Also playing a role throughout all of this are the concepts of reverberation and delay. Reverberation and delay are two distinct and separate signal processes that are oftentimes erroneously assumed to be synonymous and interchangeable. This is due to the fact that they are closely related concepts but, in the end, also incredibly different. Delay is most commonly comparable to the concept of an echo. A delay is one or more distinct sound images and is the…

1.0 Construction After the submarine cable has been designed inch-perfect, it is the next step where skills of geography are required. The construction of a submarine communications cable is not an easy matter. Furthermore, it is not an inexpensive job too. Skills and knowledge are required by engineers and workers whom are laying down the submarine communications cable. To ensure that the millions of dollars invested on the cable do not go to waste, every single precaution step must be taken…

the company was eager to make money on the back of the popularity of Hawaiian music at the time. This inspired Beauchamp to place a pickup under the strings of the guitars to carry electrical signals to an amplifier. The decision to make the guitar non-resonant in the absence of an amplifier was reached due to the creation of feedback from the vibrations of the bodies of amplified acoustic guitars ((Campbell, Brody, 2008, p.…

This was my first rock and roll concert that I have ever attended. It was an amazing experience to witness live the energy of this genre of music. During the concert, the spontaneity in the artists’ improvisations, musical communications of the artists by their listening to each other’s instruments, the guitarist’s hair shaking and lively performance, the guitarist’s and the bassist’s jumps in the middle of the songs reflecting their musical expression, and the bassist’s impromptu singing in a…
