The system Digital broadcasting signals are Analog signal waves to remove that resembles a wave (sine wave) tyrosine converts it into squares (Square Wave) in the form of a binary number (Binary Digits) by assigning a value of 0, whereas there is no signal and has a value of 1, while Digital signals are signals, so it is not. The size of the constant, the signal for a short time, and then change the value to change it to Digital signals are electrical induction to open/close. The rate of electrical induction to send image data code this is called binary digit bit. Rate (Bit Rate) signal transmission system, it has a great feature is the Digital audio clarity and can send multiple items in the same frequency bands. In the Digital broadcasting transmission system radio stations need to modify several devices from the system is Analog Digital Tuner rear system it needs to modify a Digital System.
