Advantages And Disadvantages Of Oscillator

Advantages and Disadvantages of Oscillators

An oscillator is an electronic circuit that produces a periodic, oscillating electrical signal without any input. Oscillators most commonly produce a sine wave, but can also produce a variety of other waveforms including sawtooths, square waves and triangular waves. They are a vital component of many electronic devices ranging from televisions to radios to computers. Here are some of the advantages and disadvantages of oscillators :


  • Simple: Oscillators are relatively easy to construct, making them suitable for a wide range of applications.
  • Versatile: A single oscillator can produce a range of waveforms, making it a suitable component for many devices.
  • Accurate: Oscillators are capable of producing highly accurate waveforms, making them suitable for applications where precise timing is essential.
  • Low Cost: Oscillators are relatively inexpensive and simple to build, making them a cost-effective choice for many electronic devices.


  • Sensitive: Oscillators are sensitive to changes in external conditions such as temperature, making them unsuitable for certain applications.
  • Viability: If a component of an oscillator fails, the entire circuit can be rendered inoperable, making it unsuitable for modern high-reliability applications.
  • Power Consumption: Oscillators require an external power source in order to operate, increasing the power requirements of a device.
  • Noise: Oscillators can generate noise, making them unsuitable for certain applications.

Overall, oscillators are an essential component of many electronic devices and have their own unique advantages and disadvantages. They are versatile, easy to construct, and relatively inexpensive but are sensitive to external conditions and can be noisy.
