The number of amplification stages of a radio receiver is

The correct answer is option 1):(two)

Concept:

• The functional block diagram of a simple radio receiver is shown

• The receiving antenna receives the radiowaves from different broadcasting stations.
• The desired radiowave is selected by the radio frequency amplifier, which employs a tuned parallel circuit.
• The tuned RF amplifier amplifies this selected radiowave. The amplified radiowave is fed to the detector circuit which consists of a PN diode.
• This circuit extracts the audio signal from the radiowave. The output of the detector is the audio signal, which is amplified by one or more stages of audio amplification.
• The amplified audio signal is given to the loud speaker for sound reproduction.
• There are two amplifier used
