In Rf tuning, what is the first local oscillator?(a) Quartz oscillator

1.	In Rf tuning, what is the first local oscillator?(a) Quartz oscillator(b) Frequency synthesizer(c) Magnetic oscillator(d) Electric oscillatorsThe question was asked in homework.I need to ask this question from Ground Stations topic in chapter Satellite Communication of Avionics
Answer» Right choice is (b) FREQUENCY SYNTHESIZER Easiest explanation: In RF tuning, the first local oscillator is made adjustable. Generally, a frequency synthesizer is USED in this application. The frequency synthesizer GENERATES a HIGHLY stable signal at selected frequency increments.
