I remember doing a simple problem in chapter 1 and having to reference the appendix for a trig formula. But, the problem wouldn't work out nicely... so I looked online and realized that the trig formula had a typo in it (sine and cosine switched)!

That was only a sign of more things to come. You can't read two sentences without coming over a typo. There are grammar errors, mislabled graphs, and typos in equations. Some of the typos are very confusing too.

Here is a list of typos that my professor found in one chapter:
294 Eq. 8.10 Last term should be i(0)L
297 Table 8.1 Symbol for impedance of inductor and capacitor should be ZL(s) and ZC(s).
298 4th line: we see that as a → 0 (not t → ∞)
299Eq. 8.25 e-sτ instead of e-st
312First term of right side of first equation should be k1/s (not k1/2).
315 Example 8.5: "In the mechanical system of Example 8.4..." (not Figure 8.10).
321 Eq. 8.58 First limit should be t → ∞ (not s → ∞).
321 Third equation: integral sign missing in last term.
321 Example 8.8 "Use the final value theorem to find the final value of x(t)..."
321 lim t → ∞ missing from last equation in proof of Eq. 5.58
321 Example 8.8 0.5 should be 0.46 in last equation and the final value is 0.92.
321 Example 8.8 "...letting t → ∞ in the..." (not t → 0).
332 Problem 8 ke = 1000 dynes/cm (add units)

It's like that through the whole book. It's just terrible.

I am a biochemistry student who is starting a Bioengineering PhD program in the fall and I have found this book to be a great intro into signals and systems. The example problems in MATLAB have been very helpful and clear. Despite the occasional typo (which is normal for a first edition), it is in general well-written.
