A carrier signal with a frequency of 100 MHz, frequency by band limited information sign with 2 KHz modulating. Maximum frequency deviation of the FM sign (Δf) 25 KHz and information sign amplitude (Am) If it is 15.7 Volts;

a) Calculate the bandwidth of the FM sign?

b) The bandwidth of the FM signal is doubled and the frequency modulation constant is taken if kf = 10000

What can be said about the signal to noise ratio (SNR) of the signal, why?

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
