Pelajari tentang elektronik Digital Elektronik 1.1 Sistem Nomor Elektronik Apa Tujuan anda setelah belajar dalam Modul 1.1 Setelah mempelajari bagian ini, Anda harus dapat: Tahu nilai-nilai dasar sistem bilangan yang umum digunakan. • Decimal • Binary. • Oktal. • Heksadesimal. Memahami metode untuk memperluas ruang lingkup sistem nomor. • Eksponen. • Terapung notasi titik. • bentuk Normalised. Tahu bagaimana nilai-nilai numerik dapat disimpan dalam sistem elektronik • Bits. • Bytes. • Kata-kata. • Register. Sistem Nomor Kebanyakan sistem nomor mengikuti pola umum untuk menuliskan nilai angka: Sejumlah tetap nilai dapat ditulis dengan karakter numerik tunggal, maka kolom baru digunakan untuk menghitung berapa kali nilai tertinggi dalam sistem penghitungan telah tercapai. Jumlah nilai numerik sistem ini menggunakan disebut dasar sistem. Misalnya, sistem desimal memiliki 10 karakter numerik dan memiliki basis dari 10:

Creating a HI-FI stereo FM transmitter to transmit music around the house or even for your own radio station can be sometimes really challenging. Designing preamplifiers, buffers, RF oscillators, modulators, and RF amplifiers add to the difficulty of building an FM transmitter. With this circuit, we can minimize the complexity of creating stereo FM transmitters. This circuit uses a HI-FI Stereo FM Transmitter IC. This IC serves as the low power stage of the transmitter and it can be powered by a 1.25V-2.5V DC supply voltage. It consists of a stereo modulator that creates stereo composite signals, an FM modulator that creates FM signals, and an RF amplifier. The stereo modulator develops composite signals made up of a MAIN (L+R) signal, a SUB (L-R) signal, and a pilot (19kHz) signal using 38kHz crystal oscillator. The FM modulator has carriers on the broadcast band (88-108 MHz). The RF amplifier transmits the stereo encoded FM signals and is also a buffer for the FM mo

This project introduces the use of PCA21125 as one of the components of this digital clock. It is a real time clock made in CMOS technology and calendar optimized for low-power consumption with an operating temperature up to 125 degree Celsius. Data is transferred via a Serial Peripheral Interface (SPI-bus) with a maximum data rate of 6 Mbit/s. The device displays the current time and date with the use of an LCD. ATMEGA8 microcontroller was chosen for its high prevalence and low price. This microcontroller can be used as a DIP- housing 28 and a housing SMD execution TQFP- 32. Resistor R3 is needed to prevent random noise at terminal PC6. The LCD display is connected to the microcontroller for four-bit system. The variable resistor R2 is required to adjust the contrast of displayed symbols. Rotating this resistor obtains the most precise indications on the screen. The LCD backlight is organized through the conclusion of "A" and "K" on the display
