i have a question, i am solving a mathematical problem by using a code in VB, the question is to calculate the output noise by givning ten different inputs by the user in textbox. the inputs wil be entered in the equation below like, B, Tin,Tfd,Te1,Te2,Te3,Gf,G1,G2,alpha, length

the formula for output noise power is ,

N= K*T*B

where K = 1.38*10^-23(boltzmann's constant)

B(bandwidth) = 5000(Hz), and

T = Tin+Tfd+(Te1/(Gf))+(Te2/(Gf*G1))+(Te3/(Gf*G1*G2))

where Gf = 10^(Gf/10) and G1 = 10^(G1/10), G2 = 10^(G2/10) and Tfd = (10^(Lf/10)-1)*290; where Lf=(alpha*length)

and, in coding i did that in this form;

Private Sub Command1_Click()



Dim Tin As Double

Dim alpha As Double

Dim length As Double

Dim Te1 As Double

Dim Te2 As Double

Dim Te3 As Double

Dim Gf As Double

Dim G1 As Double

Dim G2 As Double

Dim lf as Double

Dim tef as Double

Dim B As Double

Dim result1 as double

k = 1.38 * 10 ^ -23

lf = (a * l)

tef = (10 ^ (lf / 10) - 1) * 290

tequ = ts...
