+\subsection{Analysing the problem}
+In modern times the need for a radio has obviously fallen, with the rise of TV sets and the internet, generally being a faster method of receiving information, however in some situations, a radio is still preferable. For example if you are hiking, you may be out of range of cellular data, and a TV would require, power and signal which you wont have; in a situation like this a radio is perfect, being a low power device, that can receive important safety information. Similar situations can be drawn for all outdoor use of electronics, weather its a hike, sailing trip, off grid living or something else, a radio can be a valuable tool for keeping up to date on important information.
+
+I believe creating a simple radio receiver will be helpful to those looking for the capabilities of listening while on the go, it can be small and practical as someone who hikes a lot myself, I would enjoy this project, so I can listen to the news, music or a podcast while hiking, without needing to worry about draining my phones battery, which is better saved for emergency situations.
+
+\subsection{Design specification}
+The product I would like to build for this project is a simple radio receiver, it should receive signals, demodulate them, amplify them and play them out of a speaker. To add something more interesting to my project, I will add a bar graph display that displays the intensity of the currently playing sound. 
+
+The design should focus on simplicity, as less points of failure should result in something reliable. I have in the past, owned a radio for hikes, however it had multiple dials which all clogged with mud, and now it doesn't work; I would much rather have something that is pre tuned to my desired values and left as is.
+
+\section{System design}
+
+\subsection{Subsystem designs}
+To build my project, I will split it into manageable subsections, that can each be tested and evaluated. The subsystems I intend to build are:
+\begin {description}
+	\item[The receiver:] \hfill \\
+	This will be the part of my system that detects the weak incoming radio signals from the outside world weak incoming radio signals from the outside world.
+
+	\item[The initial amplifier:] \hfill \\
+	This will boost the small incoming signal to a more reasonable size, to make it easier to process, working with small values may result in signal degradation.
+
+	\item[The demodulation system:] \hfill \\
+	This will take the incoming wave, that will be encoded as an AM signal (not FM), and convert it to the audio wave I wish to detect.
+
+	\item[The volume control amplifier:] \hfill \\
+	This will be another amplifier that controls the volume of the signal, before it reaches the audio system.
+
+	\item[The audio intensity meter:] \hfill \\
+	This will consist of a micro controller (Picaxe 18M2 using the WJEC assembler), and a bar graph, and will show me the current volume of my system.
+
+	\item[The push pull power amplifier:] \hfill \\
+	This will boost the power output of my system, allowing it to drive a small speaker (or perhaps headphones), and output the desired audio.
+
+	\item[The speaker:] \hfill \\
+	This is the audio output of my system.
