Types of Transistor Oscillators: A transistor can be operated as an oscillator for producing continuous undamped oscillations of any desired frequency if tank (or oscillatory) and feedback circuits are properly…
Frequency Stability of Oscillator: An oscillator having initially been set at a particular frequency does not maintain its initial frequency, but instead drift and wander about in frequency, sometimes uniformly…
What are the Essential Components of an Oscillator? The Essential Components of an Oscillator are namely, Oscillatory circuit or frequency determining element. Amplifier. Positive feedback network. The oscillatory circuit or…
What is Oscillator? - Types of Oscillators: An oscillator is the basic element of all ac signal sources and generates sinusoidal signals of known frequency and amplitude. It is one…
Light Dependent Resistors (LDRs) - Definition, Construction, Workings and Applications: Light dependent resistors (LDRs) are made from cadmium sulphide containing no or very few free electrons when not illuminated. Its…
Photoconductivity - Definition, Working and its Applications: Photoconductivity - When excess electrons and holes are produced in a semiconductor, there is a corresponding increase in conductivity of a sample as…
What is Optoelectronic Devices? Optoelectronics is the technology that combines optics and electronics and the devices based on this technology are known as optoelectronic devices. These devices include emitters, sensors…
