Resonant Circuit in Mobile Phone – About Resonant Circuit Resonant Circuit in Mobile Phone is combination of capacitor and coil. Resonant Circuit passes specified resonant frequency. Here I Explain Definition and Theory of Series and Parallel Resonance. Resonant Circuit in Mobile Phone We have already learnt about SMD Resistors , SMD Capacitors  and SMD coil . In any circuit, a resistor influences flow of AC and DC supply whereas coils and capacitors are used to influence AC supply only. The circuits made by connecting capacitors and coils in series or parallel are called tuned circuit or resonant circuit. Resonant or Tuned circuits are capable of specified frequencies from many frequencies. Generally resonant circuits are combination of capacitor and coil. Resistance is used to control the value of signal. Every resonant circuit passes a specified value of frequency. This frequency is called resonant frequency of that type of circuit . In other words we ...

Frequency and Frequency Band in Mobile Cell Phone Frequency and Frequency Band – The wave produced per second from a medium is called frequency. Specific range of frequencies is called frequency band.. Lear more about Frequency and Frequency Band used in mobile phone and telecommunication. What is Frequency? The wave produced per second from any medium is called frequency and is denoted by “ F ”. Unit of measuring frequency is “ Cycles per Second ”. It is denoted by C/S . “ Cycle per Second ” is also known as “ HERTZ ” Unit. Hertz is denoted by Hz . C/S and Hz are same units. The units bigger than Hertz are correlated as follows: 1000 Hz (Hertz) = 1 KHz (Kilo Hertz) 1000 KHz = 1 MHz (Mega Hertz) 1000 MHz = 1 GHz (Giga Hertz) Frequency Bands in Mobile Phones A specific range of frequencies which are used in  telecommunication  for a particular purpose is called band. This is a part of long series of frequencies. Band Width or Bandwidth Bandwid...

Integrated Circuit (IC) – IC Basic Tutorial In This IC Basic Tutorial will help you learn the basics of an IC or Integrated Circuit. What is an IC or Integrated Circuit? Integrated Circuit or IC is an SMD Electronic Component made up of combination of several transistors, diode, resistor, capacitors in a tiny semiconductor chip. Integrated Circuit Electronic Components or IC are of small size and very light weight. They produce excellent results at low power. IC Basic Tutorial I have divided this tutorial into several small parts for ease of reading and understanding. Read these sections to learn the basics of on IC and how it works. What is an IC Made Up Of Components used in an IC are not visible from outside. These are built in a semiconductor chip and cannot be removed. Capacitors of more than 30 PF value are not used in IC nor can inductors and Transformers be mounted inside the chip of an IC. Thousands and millions of bi-polar Transistors and CMOS  (...

Nokia Secret Codes  2019 (Working)                             NOKIA SECRET CODES     Nokia mobiles are very popular mobiles. Before Android and iPhone, everybody liked to use Nokia phones. Nokia mobile phones are reliable and easy to use. Nokia has some secret mobile codes. By using these code we can do some interesting things like reset phone, know manufacturing date or much more. These codes are loopholes by Nokia to help its users in different situation. Sometimes, we accidentally forget our phone password or our device malfunction due to some bug. We can easily restore our phone to firmware and reset its password to default settings. We can also surprise our friends with Wonderful things by using these code. Be the master of Nokia mobiles. Nowadays many mobile version provide little hidden codes which help us when something goes wrong or our device got stuck. We already listed those ...
