In sp-m1-2-digital-signals-complex-numbers
section 2.2, code cell, line 7

It looks like this should say:
print(c)

In sp-m1-3-sampling-sinusoids
section 3.1

”
For a given sampling rate 𝑓𝑠

(seconds/sample) we can work out the time between each sample as:

𝑡𝑠=1𝑓𝑠

The units of 𝑡𝑠
is seconds/sample.
“

I think fs should be “samples/second” while ts is “seconds/sample”?

Thanks Ross! I’ve fixed it in the github repo.

In sp-m2-2-fir-filters,

“all the input values get scaled up, with the the middle of the filter window get biggest relative increase.”

What should it say?

[Catherine Lai]

Sorry for the confusion! Better phrasing would be:

‘all the input values get scaled up as all the coefficients in b are greater than 1. The input 2 steps (i.e., x[n-2]) before the current output time step (i.e., y[n]) will get the biggest increase (i.e., b[2]=1.5)’.
