How are digital signals in radio broadcast converted to analog signals inside digital transmission equipment before sending the signals to the antenna for transmission?
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
What is the main advantage of digital transmission over analog transmission?
digital signal is less susceptible to signal degradation due to the nature of it's transmission signal which is either on or off and therefore less errors occur as analog is prone to signal degradation and loss that is why digital tv is crisp and clear and analog is somewhat blurry in comparison, also with higher bandwidth achievable by digital transmission more data is able to be transmitted.
What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
What are the differences between analog and digital filters?
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
What was before digital transmission?
Analog transmission came before digital ones
What was before digital?
Analog transmission came before digital ones
Why digital transmission is preferred than analog transmission?
Faster responce.
What is digital transmission of analog data?
it means that you digitize analog data for transmission . Like 2 computer that chatting .
What are the characteristics of digital transmission over analog?
Error can be easily detected in digital.
Different types of signal encoding technique?
n Digital data, digital signal n Equipment less complex and expensive than digital-to-analog modulation equipment n Analog data, digital signal n Permits use of modern digital transmission and switching equipment n Digital data, analog signal n Some transmission media will only propagate analog signals n E.g., optical fiber and unguided media n Analog data, analog signal n Analog data in electrical form can be transmitted easily and cheaply
What are the two kind of transmission?
Digital and analog <><><> In automobile terms, manual and automatic.
What is adaptive modulation?
Adaptive delta modulation is a analog-to-digital and digital-to-analog conversion technique which is primarily used for voice transmission data and can be used for multiple purposes.

Why would digital data have to be modulated onto an analog signal?
For transmission through a radiowave.
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
