Practical 15 level a and mu-law companders
WebOct 3, 2024 · We now take a look at pulse amplitude modulation (PAM), a sort of hybrid between analogue and digital modulations. If we observe Fig. 8.1, we see how a PAM signal is produced.At time \(t=kT\) we hold the signal m(t) at that value, \(t=kT\) for a period of time equal to \(2\tau \) (the width of the pulse; this convention is adopted as per Fig. 2.30). WebNov 27, 2006 · The simple difference is that A-Law provides better dynamic range than u-law, but u-Law gives lower distortion for low level signals. From the limited comparisons I have been able to make, I can't pick a consistent difference between them for practical purposes. User #38927 3428 posts.
