CHAPTER 1
Square Waves
To preserve the shape of the pulse at the receiver the bandwidth of the r.f. and i.f. amplifiers must be sufficient to amplify all frequencies extending 2.5 Mc/s either side of the centre frequency, i.e. in this example the r.f. and i.f. amplifiers must have a bandwidth of 5 Mc/s to avoid distortion.
