This is my project so I need your help. Can you help me. Thank you.

Answer 1

Low pass filter w_c = 1824 rad/sec A_v = (22, 48 d B) gain at w implies 3776 is greaterthanorequalto , 98 Assume Rc low pass filter maximum gain obtain when f = 0 V_s (s)/V_1 (s) = 1/ 1 + S_cr (transfer function)S = j w A_v (s) = K_1/1 + jwcr w_c = 1824 implies 1/ RC, 20 log (V_0/V_1) = 2248 d B maximum gain is not more than any low pass filters at w = 3776 A_v greaterthanorequalto -1798 A_v = 1800 d B mode A_v = 1/squareroot 1 + j R c (3376) implies at w rightarrow 20 Log (AV) = -1800 Log (A_v) = -1800/20 = -90
