In the printed notes given out in the, a few, mostly, typographical errors were not spotted in time.
I corrected them before posting on the Web. This is the list:

Basic material
p20. The low pass filter rolls off at 6db/octave, as it correctly says on the next page, NOT 3dB per octave.

Fourier transforms
p9. The original plot was for sin(wa)/w, with a = 4, not 2sin(wa)/a. The plot on the web shows 2sin(wa)/a with a = 2.
p10. The wrong figure was originally pasted in for the phase of the bandpass filter.
p13. At the bottom of the page, the Fourier component frequencies for cos(w₀t)cos(w₁t) should be obvious.
    It was mis-typed in the original.
p14. A minus sign was missed out, which was pointed out. Later F₀ appeared as F0.
p15.   in line 3, some "f"s appear as "d"s
p19 was added after the notes were printed, so subsequent pages are renumbered.

Sensors and transducers
p4 . In line 2, "source" was printed for "load" in two places. They should be obvious.

Transistor amplifiers
p23. On differential amplifiers, in line 3, it should say R_E and not R₁
     ie V_E1 = V_A + I₁R_E  andV_E2 = V_A + I₂R_E

Data transmission
The results for open circuit and short circuit termination were typed the wrong way round.
(It is a real mystery how this one slipped through! - see the formulae above)

open circuit termination  Z_L = *
    V_ref/V_inc = +1       V_L/V_inc = 2     reflected signal = incident signal
short circuit termination Z_L = 0
    V_ref/V_inc = -1       V_L/V_inc = 0     inverted fully reflected signal

Pulse shaping
p4. There were a few typographical errors

ADCS
p1. The definitions of Integral and Differential Non-Linearity were typed the wrong way round.

z-transform
The definition of z had an incorrect minus sign:  z = exp(s*t)
 
 

Let me know if there are any I haven't spotted!
