📱 راز های جلوگیری از خرابی باتری گوشی موبایل که باید بدانید
📌 برای اینکه عمر باتری گوشی خود را افزایش دهید ، اجازه ندهید شارژ باتری شما کمتر از 15% شود ، به محض رسیدن به 15% آن را به منبع شارژ متصل کنید . از آن طرف هم به محض رسیدن به 80% باتری خود را از شارژ بکشید.
📌 در هنگام شارژ با گوشی کار نکنیم !
📌 باتری گوشی را با شارژر اصلی شارژ کنید
📌 طولانی مدت با گوشی خود بازی سنگین نکنید !
📌 گوشی را در مکان های گرم قرار ندهید !!

Digital Signal
A digital signal is a signal that represents data as a sequence of discrete values. A digital signal can only take on one value from a finite set of possible values at a given time. With digital signals, the physical quantity representing the information can be many things:
1- Variable electric current or voltage
2- Phase or polarization of an electromagnetic field
3- Acoustic pressure
4- The magnetization of a magnetic storage media
Digital signals are used in all digital electronics, including computing equipment and data transmission devices. When plotted on a voltage vs. time graph, digital signals are one of two values, and are usually between 0V and VCC (usually 1.8V, 3.3V, or 5V).

Analog Signal
An analog signal is time-varying and generally bound to a range (e.g. +12V to -12V), but there is an infinite number of values within that continuous range. An analog signal uses a given property of the medium to convey the signal’s information, such as electricity moving through a wire. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information. Analog signals are often calculated responses to changes in light, sound, temperature, position, pressure, or other physical phenomena.
When plotted on a voltage vs. time graph, an analog signal should produce a smooth and continuous curve. There should not be any discrete value changes.

What is a signal?
A signal is an electromagnetic or electrical current that carries data from one system or network to another. In electronics, a signal is often a time-varying voltage that is also an electromagnetic wave carrying information, though it can take on other forms, such as current. There are two main types of signals used in electronics: analog and digital signals.
