HWN - Hardware Design Interview: HPF

Hi fellow (and future) engineers!
Patreon: / hardwareninja
We're used to seen integrators (i.e. active low pass filters) as questions for interviews. However, can you answer a similar set of questions when it's an active high pass filter instead?
Welcome back to another episode of Hardware Ninja! Ever wondered how to get a job as a Hardware Designer in some of the top tech companies like Microsoft, Google, Tesla, Apple, Facebook, etc?
The interview process employs many application based questions whether you're a recent college grad or an experienced applicant. It doesn't matter if you want to work for Elon Musk, Tim Cook, or the up and coming start-up you heard about. We're here with curated material of real life technical interview questions.
Please consider subscribing to the channel and supporting our movement. Prospective job seekers (including yourself some day) will benefit from this resource.

Nice video, thanks for sharing it :)

[@narendramane2727]

thanks for video

[@tehepicjarebear]

Anybody know where short questions like this can be found and practiced?

[@Warboss777]

Is this considered an analog design question?

[@roswaldfrancis463]

The time constant is RC/101. The resistance seen looking at the negative terminal is R/101.

[@biswajit681]

Why time constant is RC/101 .. isn't it RC*101

[@narendramane2727]

when input V- is 0.99 why output goes to +0.99 ..isn it should be zero ? since no input is given and both terminals at same voltage? something to quickly think about this circuit is its differential amplifier, differentiation of square wave is impulses at other end of capacitor..

[@TeHa94]

The Output does whatever it takes to equalize both inputs. In that case the opamp outputs 0.99V to compensate the offset.

[@biswajit681]

What if bandwidth is finite and supply is not infinity ....is it saturated at supply voltage and the response will comparatively slower due to finite bandwidth

[@narendramane2727]

yes..with finite bandwidth i can not respond quickly to input changes and will take some time to settle

[@divasks8773]

Difference bw slew rate and Bandwidth??
