|
|
| Question 2: Here a small audio stage is used to ________ a low power stage; the output of this stage is then amplified using a linear RF amplifier. | |||
|
|
| Question 3: Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a ________ carrier wave. | |||
|
|
| Question 4: Types of radio emissions, for the emission types designated by the ________ | |||
|
|
| Question 5: In 1982, the ________ (ITU) designated the various types of amplitude modulation as follows: | |||
|
|
| Question 6: A simple detector at the transmitter output (which can be little more than a loosely coupled ________) recovers the audio signal, and this is used as negative feedback to the audio modulator stage. | |||
|
|
| Question 7: This approach is widely used in practical medium power transmitters, such as AM ________. | |||
|
|
| Question 8: A wide range of different circuits have been used for AM, but one of the simplest circuits uses anode or collector modulation applied via a ________. | |||
|
|
| Question 9: In terms of the positive frequencies, the transmission bandwidth of AM is twice the signal's original (________) bandwidth—since both the positive and negative sidebands are shifted up to the carrier frequency. | |||
|
|
| Question 10: (Contrast this with frequency modulation, also commonly used for sound transmissions, in which the ________ is varied; and phase modulation, often used in remote controls, in which the phase is varied) | |||
