Homework Help Overview

The discussion revolves around a waveform problem from past exam papers, focusing on concepts related to frequency, time period, and sampling rates in the context of an upcoming test.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the calculation of the time for one complete cycle and the corresponding frequency. There is uncertainty regarding the final part of the problem, particularly about the sample rate and its relation to the sample period.

Discussion Status

Some participants have attempted to clarify the requirements of the problem, noting the specific sampling period mentioned. There is an ongoing exploration of how to interpret the question regarding the information transmission rate.

Contextual Notes

The problem specifies a sampling period of 1.0 microseconds, which is central to the discussion about the sampling frequency and information transmission rate. Participants express confusion over the wording of the question.

I'm doing some past exam papers to revise for my test on thursday. And I can't work out the last question in this problem.

I worked out the time for one complete cylce is 50 microseconds, and the frequency is 20,000Hz, 1/Time period. I can't work out the last bit though.

I think they are just asking for the sample rate, which is related to the sample period, which they give you. Not sure if it's any more compilcated than that...
 
so its 8bits s-1?

No. The problem says, "The waveform is sampled every 1.0us", and then asks for the corresponding information transmission rate or something. The wording is a bit off, but I think they just want to know the frequency of the waveform sampling, which you get from the 1us period number.
