Sketching the Dependence of l versus h on Cartesian AxesThe distance l from a point at a height h above the Earth's surface to the horizon can be approximated using Pythagoras theorem by the expression:
l = h * SQRT(1 + (2*re/h)) , where re is the radius of the Earth.
(a) Sketch the dependence of l versus h on Cartesian axes.(b) Thus determine approximations for l by taking limits associated with the view expected by:(i) an astronaut in space;(ii) a person on a beach.

A baseband sine wave signal with frequency 4.0 kHz is modulated onto a carrier at 1.050 MHz using DSB-LC AM. What are the frequencies of the sidebands of the RF signal?
Baseband digital trnamission and multi level coding, A baseband digital data link transmits polar binary NRZ current pulses at a rate of 1.0 Msps. The link uses ideal RRC filters with roll off factor r = 0.5.
What is the maximum symbol rate for this link and the number of bits per symbol? What format would you recommend for the transmitted current pulses on this baseband link?
