Oscillators and Waveform Generation Types
Q. Match the following : Types Waveform Generation Type
a. RC Oscillator ---------------------------------- 1. Saw-tooth wave
b. LC Oscillator ----------------------------------- 2. Sinusoidal wave
c. Crystal Oscillator ----------------------------- 3. Square wave - Published on 23 Oct 15a. A3, B2, C1
b. A2, B3, C1
c. A1, B2, C3
d. A1, B3, C2
ANSWER: A2, B3, C1
The type of waveform generation by an oscillator totally depends on components used in the circuit. Hence, they can be sinusoidal if RC components are used while they can be square if LC components are used & even they can be saw-tooth or triangular if crystal oscillator is used. Crystal Oscillators are stable to maximum extent as compared to that of RC & LC oscillators due to higher figure of merit (Q). However, crystal & LC oscillators find their applications in generation of high frequency signals while RC oscillators are intended for audio-frequency applications.
