4. a) A sensor produces a baseband measurement signal m(t) that has a B=5 kHz bandwidth. This signal will be digitised using Nyquist rate sampling and L = 8192 level quantisation. What is the resulting bit rate of the digital output. b) Find the minimum signal-to-noise ratio (SNR) in dB for error-free communication of 5 Mbps (Mega bits per second) digital stream over a channel with a bandwidth of BWc = 10 MHz. c) An engineer is designing a radar to have a range resolution of 100 m and a cross-range resolution of 100 m at a range of 10 km. The carrier frequency of the radar is fe = 1 GHz. A circular antenna aperture will be used. State clearly the design choices that will satisfy these two requirements. Find the relevant numerical values. d) Find the noise power in Watts for a radar receiver with a bandwidth of B = 50 MHz, an operating temperature of To = 290 K, and a noise figure of F = 3.
