Interview Question

Software Consultant Interview Austin, TX

You have someone speaking in a microphone. How would you

  record someone's voice? If there was noise, where would you cancel it out on the signal(beginning or end of the wire)? How would a longer wire affect the signal?

Connect a microphone to a computer. Use a D/C converter. A longer wire would cause a delay in the signal.

No, a longer wire would be more susceptible to noise.
