Signal generators:
reference (tuning equipment)
source - such as electronic keyboards
beat frequencies - as in a superheterodyne radio
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
Quartz crystals are used in piezoelectric mode as stable frequency references for oscillators. The quartz is shaped and polished to the size and thickness that produces the desired frequency when stimulated.
An LM324 IC contains operational amplifiers. LM324 ICs can be used for different purposes in circuits, such as oscillators, rectifiers or oscillators as well.
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
Benjamin Parzen is known for his work in statistics and probability theory. He contributed to the field of kernel density estimation and also wrote a book titled "Modern Probability Theory and Its Applications."

Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
