The "C" in RC is capacitance, and at high frequencies, the C will shunt the signal more than at lower frequencies. The loss through the cap will climb right along with frequency. And as the cap's performance goes down, so, too, does the circuit performance. RC oscillator performance is far from linear at the top of the frequency range.

Why RC oscillators are not suitable for high frequency generation?
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
Viva questions for RC phase shift oscillator?
A phase-shift oscillator is a simple electronic oscillator circuit. It consists of an inverting amplifier element such as a transistor or op amp, with its output fed back into its input through an filterconsisting of a network of resistors and capacitors. The feddback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency, to give positive feedback.[1] Phase shift oscillators are mostly used at lower frequencies, often in the audio frequency range as audio oscillators.
What happens to RC in the new Toy Story 3 movie?
It gets high.
What is an RC oscillator?
AnswerOscillator that uses two passive elements for the timing. Namely resistor and capacitor.AnswerIt's an oscillator whose frequency-determining "tank" does not contain an inductive element, like a coil. These are good for extremely low frequencies--down to a few Hertz--but LC oscillators are better at radio frequencies.AnswerAn Rc oscillator is an oscillator that uses 3 or more phase shift networks, ( a network of a capacitor and resistor) as a frequency determining network (tank circuit) and a transistor to amplify that output, that only allows a certain frequency through by only letting the frequency that is able to shift 180 degrees out of phase through. And also has a feedback network from the collector (of the transistor) circuit, to compensate for circuit loss to oscillation.
Where RC network is used in electronic and communication circuits?
Uhhh... the short answer is "everywhere".
What are the applications of RC phase shift oscillator?
RC phase shift oscillators are used for musical instruments, oscillators, voice synthesis, and GPS units. They work at all audio frequencies.
What is the advantages of L-C oscillator circuit?
At high frequencies for rc oscillators stray capacitances comes into act so q value reduses where for lc circutes q value is high

Why RC circuit is preferred over RL circuit in waveshaping?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
Why we don't give input connection and there is only output connection in RC shift oscillators?
beacause the supply is the input and the output is the square wave
Why RC coupled amplifier is called audio amplifier?
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.
