1. The frequency of Colpitts oscillator is expressed as (Where L is inductance and C is the effective capacitance) a) 1/(4ᴨ√LC) b) 1/(2ᴨ√LC) c) 1/(3ᴨ√LC) d) √3/(2ᴨ√LC) AnswerAnswer: b [Reason:] The frequency of colpitts oscillator is expressed as 1/(2ᴨ√LC) where L is inductance and C is effective capacitance. 2. Colpitts oscillator uses which type of…
