It is been a long time since I wrote something on the website. However, I worked this week. Indeed, the purpose of the week was to choose the components for our project. We decided to focus on the receivers because the architecture of them are more complex. To help us to design the amplification of the signal receive is the coils, we met some experts and teachers of our school. They guided us in our researches.
So, we have two possible architectures for our receivers. One of them is based on the use of a low noise amplifier, a programmable gain amplifier and an ADC. The second is to use a component, an Audio Codec, that includes all these features. However, we didn’t manage to choose one of the possibility. Moreover, we worked on the whole architecture, so we choose our microprocessors, our battery and some other stuff.
Now, we may begin to draw our schematics on Expedition PCB.
