I have no idea what this is about. Can someone rephrase this article in similar terminology please? I encountered it while reading through Modern Digital and Analog Communication Systems by Lathi 4th edition on page 50 section 2.7.4 Some Examples of Generalized Fourier Series. — Preceding unsigned comment added by 68.126.206.55 (talk) 19:13, 9 March 2012 (UTC)
The Walsh functions consist of trains of square pulses with the allowed states being -1 and 1, such that transitions may only occur at fixed intervals opf a unit time step.
Walsh functions were used by electrical engineers in 1890s and were introduced into Mathematics in 1923
- It would be great if you could incorporate that into the introduction. I have no knowledge on the subject. X-Fi6 (talk) 08:06, 11 February 2013 (UTC)
