Which hardware component is not present in Superheterodyne transmitter? Digital to Analog Converters Analog to Digital Converters Local Oscillators Low-Noise Amplifier
Answers
Answer
No complicated modulator hardware is present in superheterodyne transmitter. In transmitters many correction and equalization stages are being used after modulation. In direct modulation these stages must be created isolatedly for each output RF (which is also called channel).
modular hardware can be defined as an process which divides a big system into smaller system or parts and those parts are called modules which can be independently created and then used in different systems
"The hardware which is not present in Superheterodyne transmitter is Analog to Digital Converters. This transmitter is a television or radio transmitter.
In a communication system, there is transmitter and receiver. Their parts changes according to the requirement of the signals to be sent.
In a transmitter, the general parts are amplifier, modulator (Digital to analog signal), oscillator. Since, the signals are only passed in electromagnetic wave (analog signal). There is no analogy to digital converter in transmitter whereas it is present in the receiver."
