Abstract

Penganalisis spektrum mengukur besarnya sinyal input versus frekuensi dalam rentang frekuensi penuh instrumen. Kegunaan utama adalah untuk mengukur kekuatan spektrum sinyal yang diketahui dan tidak dikenal. Sinyal masukan yang paling umum diukur penganalisis spektrum adalah listrik; namun, komposisi spektral dari sinyal lain, seperti gelombang tekanan akustik dan gelombang cahaya optik, dapat dipertimbangkan melalui penggunaan transduser yang sesuai. Penganalisis spektrum untuk jenis sinyal lain juga ada, seperti penganalisis spektrum optik yang menggunakan teknik optik langsung seperti monokromator untuk melakukan pengukuran. Dengan menganalisis spektrum sinyal listrik, frekuensi dominan, daya, distorsi, harmonisa, bandwidth, dan komponen spektral sinyal lainnya dapat diamati yang tidak mudah dideteksi dalam bentuk gelombang domain waktu. Parameter ini berguna dalam karakterisasi perangkat elektronik, seperti pemancar nirkabel. Tampilan spektrum analyzer memiliki frekuensi pada sumbu horizontal dan amplitudo ditampilkan pada sumbu vertikal. Bagi pengamat biasa, penganalisis spektrum terlihat seperti osiloskop dan, pada kenyataannya, beberapa instrumen laboratorium dapat berfungsi sebagai osiloskop atau penganalisis spektrum. Sinyal gelombang petir yang dideteksi dengan menggunakan osiloskop digital, diolah dengan aplikasi OriginPro untuk mendapatkan pola gelombang petir yang terjadi, analisis spektrum sendiri menggunakan perhitungan FFT (fast fourier transform).

Abstract

Inverter is an electronic device that functions to change current direct (DC) into alternating current (AC) with the magnitude of the voltage and frequency can be adjusted, the output of an inverter in the form of AC voltage in the form of a square wave. Then testing with different types of Step Up CT transformers to get the test results and analysis. And the working principle of this inverter circuit is that the TIP122 and 2N3055 Transistor driver pulses are generated by the IC CD4047 pulse generator, the pulses of the Astambil Multivibrator circuit are 2 pulses with a phase that reverses 180ยบ. The Q and Q pulses are used to provide drivers to the TIP122 and 2N3055 transistors and will induce the Step Up Transformer in turn. So the Step Up Transformer will be able to induce in 2 directions from the CT point. because of the induction process, the transformer primary will provide an AC voltage of 220 volts with a square wave shape. This type of inverter can only be used for lamps, the price is cheaper because it is used to back up the lamp.

Abstract

The use of archimedes screw has shifted its use from pumps to a source of hydropower at low heads as water turbines. Archimedes srew turbine performance is influenced by several parameters including turbine submersion level, turbine tilt angle, pitch ratio, and number of blades. The contour of the lowland Jambi city that is passed by the Batanghari watershed makes the drainage potential can be utilized to become a small-scale hydroelectric power plant using screw turbines, because the contour of Jambi City is low, resulting in small water pressure although the discharge is sometimes large due to the overflow of the Batanghari river, then the choice of turbine with a low head is the solution, in this study, a study was made to calculate the potential drainage flow in the city of Jambi, whether it can be used or not.
