## Homework Statement

I've been asked to sketch and mathematically represent the pdf of 2 signals:

**(a) rep2T{5 rect(t/T) - rect((t-T)/T)}**

(b) rep2T{2 rect(t/T) + 4Arect(2t/T)}

(b) rep2T{2 rect(t/T) + 4Arect(2t/T)}

A(t) is the lambda function

A(t) = 1- t for 0 <= t <= 1

1+t for -1 <= t <= 0

Any help would be much appreciated!

## Homework Equations

I understand how to sketch the signals itself. However, how can I derive the pdf of the function?

## The Attempt at a Solution

The sketched signal is :

(a) 2T period form with a 5V amplitude rectangular lasting for 1T and -1V amplitude rectangular one lasting also for 1T.

(b) A 1T zero pulse, followed by a triangular waveform(amp = 4V) with a rect base( amp = 2V) [i.e waveform goes from 0V to 6V], the latter waveform lasts for 1T as well.

However, how I do I derive the pdf from this?
