Answer #1

Answer:

Frequencies are given, here I assumed that T-values means Time periods T = 1/f in sec

(a) f = 150 Hz then Time period T = 1/f = 1/150 = 0.0067 = 6.67 x 10-3 s = 6.67 ms (since milli second = 10-3 s)

(b) f = 400 Hz then T = 1/400 s = 0.0025 s = 2.5 x 10-3 s = 2.5 ms

(c) f = 1050 Hz then T = 1/1050 s = 0.00095 = 9.5 x 10-4 s = 0.95 ms

(d) f = 1350 Hz then T = 1/1350 s = 0.00074 s = 7.4 x 10-4 s = 0.74 ms

(e) f = 2500 Hz then T = 1/2500 s = 0.0004 s = 4.0 x 10-4 s = 0.40 ms

(f) f = 3000 Hz then T = 1/3000 s = 0.00033 s = 3.3 x 10-4 s = 0.33 ms
