Question

On a  T F ( x ( t ) ) = X ( f ) {"version":"1.1","math":"TF(x(t))=X(f)"} . La transformée de Fourrier de  z ( t ) = x ( t ) + 0.3 x ( t − T 0 ) − 0.2 x ( t − T 1 ) {"version":"1.1","math":"z(t)=x(t)+0.3x(t-T_0)-0.2x(t-T_1)"}  est égale à :

Answer

X ( f ) + 0.3 X ( f ) e − 2 j π f . T o − 0.2 X ( f ) e − 2 j π f . T 1 {"version":"1.1","math":"X(f)+0.3X(f)e^{-2jπf.T_o}-0.2X(f)e^{-2jπf.T_1}"}

Answer

X ( f ) + 0.3 X ( f − f o ) − 0.2 X ( f − f 1 ) {"version":"1.1","math":"X(f)+0.3X(f-f_o)-0.2X(f-f_1)"}

Answer

X ( f ) + 0.3 X ( f − T o ) − 0.2 X ( f − T 1 ) ) {"version":"1.1","math":"X(f)+0.3X(f-T_o)-0.2X(f-T_1) ) "}
