Hi
Could anyone give me some advice on a RC high pass filter calculation.
Is it possible to calculate the voltage gain with just the following information available, angular frequency = 1/10us.
Thanks in advance

So, with these assumptions, your corner angular frequency is 100 000 rad/sec. That is equivalent to 100/(2*PI) or 15.9 kHz. The gain at 0 Hz is 0, at f0 the gain is 1/sqrt(2) and increases up to 1 when frequency is increased.
Google RC filter for detailed information.
I hope that this isn't a school question. But, if it is, I held back the central information, the formula for calculating the gain.

In truth an active rc highpass filter will always end up having a bandpass filter characteristic.
