AI Thread Summary
The discussion revolves around preparing for a test by working through past exam papers, specifically focusing on a problem related to waveform sampling. The user has calculated the time for one complete cycle as 50 microseconds and the frequency as 20,000Hz but is struggling with the last question. Clarification is provided that the problem asks for the information transmission rate based on the sampling period of 1.0 microsecond. The key takeaway is that the sampling frequency can be derived from the given sample period. Understanding these concepts is crucial for effective test preparation.

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.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
