solve only question 1.b 1.a) Calculate the bandwidth and baud rate for an FSK signal with mark frequency 34 kHz, space frequency 26 kHz, and input bit rate 2 kbps. Use the calculator for bandwidth. 1.b Using a table of Bessel functions, determine the minimum bandwidth for the FSK signal from the previous problem (Problem 1.a). Remember that the significant bands are taken for those with amplitude > 1%. Since the table is normalized (Jo=1 at most), the significant sidebands are those with amplitude > 0.01). -- Indications: In your answer, place the result without the units and expressed in kilohertz
