In connection with oscillator, which is FALSE statement?a)Oscillator c...
Explanation:


  • Oscillator converts d.c. into a.c.: This statement is true. Oscillators are electronic circuits that generate repetitive waveforms, such as sine waves, square waves, or triangular waves, by converting direct current (d.c.) into alternating current (a.c.).

  • Oscillator is that amplifier which provides its own input: This statement is true. Oscillators are self-excited circuits that provide their own input without requiring an external signal to start oscillation.

  • All types of oscillator produce sine wave: This statement is false. While some oscillators produce sine waves, there are also other types of oscillators that can generate square waves, triangular waves, or other waveforms.

  • In phase, feedback used in oscillator is also called positive feedback: This statement is true. In-phase feedback in an oscillator circuit is also known as positive feedback, as it reinforces the input signal and helps sustain oscillation.


Therefore, the FALSE statement in connection with oscillator is that all types of oscillator produce sine wave.
