today we discussed about how to make our reciever. we saw videos about design of low pass filter, amplifier, frequency mixer. we came up with thw idea that if we pass the signal through an array of amplifier and low pass filter , we could extract the low frequency signals with our main focus on 1420 MHz signal at which we get 21 cm hydrogen line.After ward ,our seniors gave us some questions.
