Karena itulah saya coba persembahkan untuk Anda pada project Elektronika kami kali ini.: Rangkaian Elektronika : Switch Otomatis Dari Listrik Utama ke Lisrik dari Baterai/ Cadangan. (more…)
wihans web indonesia ~ wihans.info : Oscilloscope (Oscilloscope) is a set of tools for measurement and analysis of waveforms and other symptoms in electronic circuits by utilizing the input of electrical signals. Oscilloscope is basically useful for analyzing the electrical quantities (frequency, period, amplitude, phase angle, and voltage) that change with time.
Oscilloscope screen is divided into 8 squares on a large scale in the vertical direction and (more…)
wihans web indonesia ~ wihans.info : A compressor circuit shown in the schematic diagram below can produce consistent output of 1.4V P-P over entire 60dB range that is very useful for audio level/volume stabilization.
As the main components, this circuit uses a 741 opamp and JFET. With input range of 20mV to 2oV, this circuit has delay time of 0.4s (decay time) and response time of 1.2ms (attack time). The JFET is used as voltage-controlled resistor in peak-detecting control (more…)
wihans web indonesia ~ wihans.info : Audio Mixer With FET is a very simple audio mixer. Simple Audio Mixer With this FET circuit is Used for mixing (mixing) 2 channel audio signal.
Image circuit the Simple Audio Mixer With a FET on this page is a sample output for 1 channel only, if Want to stay a stereo system to make two pieces of circuit Simple Audio Mixer With this FET. (more…)
wihans web indonesia ~wihans.info : When we modulate a carrier signal with amplitude modulation, there will be four frequency components as the result.
The first is the modulating signal itself, the second is the frequency carrier, the the latest two are the difference and the sum of the carrier and the modulating signal. The spectrum of these frequencies can be seen using frequency analyzer. (more…)
wihans web indonesia ~ wihans.info : Transistors are electronic components that are designed as a current amplifier, and therefore called a transistor device (device) which handles the flow (current handling device).
Judging from the type, the transistor is divided into two, namely the type PNP (Positive-Positive-negative) and type NPN (negative -Positive-negative). Inlet (leads) into (more…)
wihans web indonesia ~ wihans.info : SMD Capacitor Keramik Coding, Kapasitor keramik SMD kadang-kadang ditandai dengan kode, yang terdiri dari satu atau dua huruf dan digit.
Yang pertama surat jika ini adalah kode pabrikan (yaitu K untuk Kemet, dll), huruf kedua mantissa dan digit yang eksponen (multiplier) dari kapasitansi dalam pF. Misalnya S3 adalah capactitor (4,7 x 10 pf ³) 4.7nF dari produsen tidak diketahui, sementara KA2 (more…)
