So am trying to find the Frequency response of a RC LPF between frequencies 100Hz-100kHz ,but i don't know what formula to use .
Trying to find the frequency response of this circuitBvU said:I don't think you mean $$1+2\pi f CR$$ as you did wwrite, but I could be mistaken.
Frequency response is ##V_{out}/V_{in} ## with a sine ##V_{in}##. Low pass means you are referring to a circuit like here
and the same recommendations apply.

no, got no ideaberkeman said:Write the KCL equation for the voltage ##V_o(t)## in terms of ##V_i(t)## and R and C. Do you know the differential equation relating current and voltage for a capacitor?
Guessed as much. Holler if you don't recognize the equations in the link I gave in #2.IronaSona said:Trying to find the frequency response of this circuit View attachment 285733
That's strange. Why should you have to do an exercise like this if you don't ?IronaSona said:no, got no idea
And it seems to me you are not interested either?IronaSona said:no, got no idea
Frequency response refers to the range of frequencies that a system or device can accurately reproduce or process. It is typically measured in Hertz (Hz) and is important in understanding the performance of audio and electronic systems.
This frequency range is important because it encompasses the majority of audible frequencies for humans, ranging from the low bass notes at 100Hz to the high treble notes at 100kHz. Many audio devices and systems are designed to accurately reproduce frequencies within this range.
There are several factors that can affect frequency response, including the design and quality of the system or device, external noise and interference, and the materials used in construction. Additionally, the frequency response can vary depending on the volume or power level being used.
Frequency response is typically measured using a device called a frequency analyzer, which sends a range of frequencies through the system and measures the output. The resulting graph, known as a frequency response curve, shows the system's ability to accurately reproduce different frequencies.
A flat frequency response means that the system or device is able to accurately reproduce all frequencies within a given range with equal loudness or amplitude. This is often considered the ideal frequency response for audio systems, as it ensures a balanced and natural sound.
