Which of the following is not an example of sinusoidal oscillator?(a)

1.	Which of the following is not an example of sinusoidal oscillator?(a) RC phase shift oscillator(b) Weinbridge oscillator(c) Crystal oscillator(d) Blocking oscillatorI had been asked this question in class test.I'd like to ask this question from Classification of Oscillator-1 in section Oscillators of Analog Circuits
Answer» The correct choice is (d) Blocking oscillator Easy explanation: A blocking oscillator is a non-sinusoidal oscillator. It produces a FREE running signal-square SHAPED and requires only a RESISTOR, transformer and one amplifying element to work. The transistor is blocked off for most of the duty cycle, producing periodic PULSES.
