will there be at least a way or trick to run two different remote control car together with the same fixed frequencies
The frequency of an RC phase shift oscillator is determined by the values of the resistors and capacitors in the feedback network. It is typically calculated using the formula f = 1 / (2 * pi * R * C * sqrt(6)), where f is the frequency in hertz, R is the resistance in ohms, and C is the capacitance in farads.
In an RC phase shift oscillator, oscillations are produced by the feedback network consisting of resistors and capacitors connected in a specific configuration to generate a 180-degree phase shift at the desired frequency. This phase shift, along with the inverting amplifier stage, satisfies the Barkhausen stability criterion for oscillation to occur. The loop gain of the circuit is unity and the phase shift of the feedback network is carefully controlled to ensure sustained oscillations at the desired frequency.
A high pass circuit can act as a differentiator because it allows high frequency signals to pass through while attenuating low frequency signals. This property causes the output to respond more to the rate of change of the input signal, making it behave similar to a mathematical differentiator.
When the time constant of an RC circuit increases, the circuit takes longer to reach steady state or fully charge/discharge. This means the circuit responds more slowly to changes in input signals. A larger time constant indicates slower transient response and reduces the frequency at which the circuit can operate effectively.
A Wien-bridge oscillator generates a sinusoidal waveform using an op-amp and a feedback network with both resistors and capacitors, while a phase-shift oscillator uses an RC network to introduce phase shifts in the feedback path to generate oscillations. Wien-bridge oscillators are typically used for audio frequency applications, whereas phase-shift oscillators are commonly used for higher frequency applications.
If two RC cars are receiving signals on the same frequency, then you can't race against each other. However, many RC cars are designed with multiple frequency capability so that the frequencies can be changed to eliminate any interference.
frequency of RC n/w is 1/2piRC
when the frequency is increased the total impedance of a series RC circuit is decrease.

RC cars are controlled by controllers of a designated frequency of radio waves. To control a RC car, you must have a controller that the RC car has a paired frequency with. A universal RC controller is non existant.
For older systems running 27MHz no binding is necessary, simply ensure the Tx and Rx are using the same frequency crystals. For newer 2.4GHz systems binding is necessary by shorting two of the pins on the port labelled 'bind'. Almost all Rx will come with a special binding plug, simply shorting these two wires.
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.
the circuit will pass waves of a lower frequency
Generally yes. Most RC helicopters have different servo frequencies programmed in to avoid this problem. It is recommended to buy mid- and higher-end RC helos that have programmable frequencies, so you can set them yourself. But if you are going to buy a three channel RC helo, your best bet is to buy two different models, or one brand that has interchangable frequency chips.
