"Buku yang berjudul "Advanced oscilloscope handbook : for technicians and engineers" ini ditulis oleh Derek Cameron. Buku ini merupakan sebuah buku panduan mengenai oscilloscope."

"Kebutuhan akan energi semakin meningkat. Saat ini, lebih banyak yang menggunakan sumber daya alam terbatas sebagai penghasil energi, seperti solar, bensin, batubara dan lain-lain sehingga banyak peneliti yang mengembangkan energi alternatif dari sumber daya alam yang dapat diperbarui, seperti gelombang laut, angin, matahari, getaran, dan piezoelektrik. Namun, penelitian mengenai piezoelektrik masih sedikit. Oleh karena itu, penulis mencoba untuk menganalisis gelombang tegangan keluaran piezoelektrik sehingga dapat dilihat bentuk serta pemanfaatannya. Penelitian ini merupakan penelitian kualitatif yang menganalisis gelombang tegangan piezoelektrik. Pengambilan data dilakukan dengan menempelkan piezoelektrik pada dinding, kemudian memukulnya menggunakan silinder pemukul yang dipasang pada sebuah motor sehingga ketika motor berputar, silinder pemukul akan mengenai piezoelektrik. Rangkaian ini kemudian dihubungkan dengan osiloskop untuk melihat gelombang yang dihasilkan. Hasilnya adalah gelombang tegangan yang dihasilkan berbentuk sinusoidal (bolak-balik ; AC) dengan gelombang positif lebih besar dibanding dengan gelombang negatifnya yang dikarenakan besar momentum tumbukan lebih besar dibanding regangan. Tegangan yang dihasilkan oleh piezoelektrik berpengaruh terhadap dimensi (luas penampang dan tebal) dari piezoelektrik.

The demand for energy is increasing. Nowadays, people often useunrenewable resources as energy, such as diesel, gasoline, coal and other so researchers are developing alternative energy from renewable resources, such as ocean waves, wind, solar, vibration, and piezoelectric. However, research on piezoelectric still small. Therefore, the author tries to analyze the piezoelectric output voltage waveform that can be seen form and utilization.

This research is a qualitative study that analyzed the piezoelectric voltage waveform. Data retrieval is done by attaching a piezoelectric on the wall, then hit him using cylindrical bat mounted on a motor so when the motor spins, the piezoelectric cylinder will bat. The circuit is then connected to an oscilloscope to see the waveform generated.

The result is a surge voltage generated sinusoidal (Alternating Current) with positive waves greater than the negative waves that because large momentum pressure greater than strain. The voltage generated by the piezoelectric effect on the dimensions (cross-sectional area and thickness) of the piezoelectric."

"Top space experts from around the world have collaborated to produce this comprehensive, authoritative, and clearly illustrated reference guide to the fast growing, multi-billion dollar field of satellite applications and space communications. This handbook, done under the auspices of the International Space University based in France, addresses not only system technologies but also examines market dynamics, technical standards and regulatory constraints. The handbook is a completely multi-disciplinary reference book that covers, in an in-depth fashion, the fields of satellite telecommunications, Earth observation, remote sensing, satellite navigation, geographical information systems, and geosynchronous meteorological systems. It covers current practices and designs as well as advanced concepts and future systems. It provides a comparative analysis of the common technologies and design elements for satellite application bus structures, thermal controls, power systems, stabilization techniques, telemetry, command and control (TTC), and orbital configurations. These common aspects are addressed in an integrated fashion to explain how all these space systems share similar design features, but also have quite specialized application packages to carry out their various missions. No other reference in print today provides such a comprehensive and in-depth guide to all forms of application satellites, including small sats as used by countries just beginning space application programs."
