Ability of d oscil ckt is to oscilt at one exact freq cald as frqncy stability...no. Of factors may cause chngs n osciltor frqncy...primary fctrs are 1)temperature chngs 2)chngs n dc power supply..chngs in these two factors causes variations in d gain of d opamp,in junction capacitances and resistances
of d transistors in an opam nd n extrnl components..so to avois thses variations v use regulated power supply n temprtr controler...
Anothr imp factor dat detrmines frqncy stability s d figure of merit Q of d ckt...the higher d Q the grtr d stability ..for this reason crystal osciltrs are far more stabl dan d RC or LC osciltrs especially at highr frequencies...RC ckts are used for audio frqncies...

What is an Unstable oscillator?
An unstable oscillator is an oscillator that cannot hold one or more of its parameters constant (e.g. the frequency drifts, the amplitude drifts).
What type of vehicle cannot travel over a suspension bridge?
What kind of bridge cannot travel over a suspension bridge.
Which of the circuits cannot be operated directly from the mains?
half center bridge voltage
What is the difference between the Carey foster bridge and meter bridge?
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
Which item would not increase voltage and generate an electrical current?
A simple resistor would not increase voltage or generate an electrical current. Resistors are used to limit the flow of current in a circuit and dissipate energy in the form of heat, but they do not add energy to the system. Therefore, they cannot increase voltage or generate electrical current on their own.
Can an audio oscillator be used to cures illness's?
No, an audio oscillator cannot be used to cure illnesses. Illnesses are medical conditions that require proper diagnosis and treatment by healthcare professionals, while audio oscillators are electronic devices used to generate sounds at specific frequencies. It's important to rely on proven medical treatments for illnesses.

London Bridge cannot rust. It is a pre-stressed concrete bridge.
What is another name for rectifier convert dc to radio waves ac?
You cannot use a rectifier to go from DC to AC. You need an oscillator.
Can humans hear ultrasound frequencies?
No, humans cannot hear ultrasound frequencies as they are above the range of human hearing, which typically ranges from 20 Hz to 20,000 Hz. Ultrasound frequencies are typically above 20,000 Hz.
