Applied Acoustics test - 11/12/2015

1) In Javascript, after defining this vector of integer numbers using your matricula:

var matN = [A,B,C,D,E,F];

evaluate the following expression:

Result=Math.floor(matN[1]+2*matN[4]-matN[5]/(3+matN[3])-matN[0]);

write resulting number:

2) In Javascript, evaluate the value of the variable Result after this piece of code:

for (i = matN.length ; i > 0; i--)

text += matN[i-1] + '|';

3) In Javascript, write the code for computing the 6 variables A,B,C,D,E,F from the variable Matricula, which contains your matricula number as a single long integer (ex.: Matricula=123456;)

write the code in the following text field

var Matricula =

var A = Math.integer(Matricula/100000)

var Mat = Matricula+'';

var B = Math.integer((Matricula-A*100000)/10000);

var A = Mat[0];

var C = Math.integer((Matricula-A*100000-B*10000)/1000);

var B = Mat[1];

var D = Math.integer((Matricula-A*100000-B*10000-C*1000)/100);

var C = Mat[2];

var E = Math.integer((Matricula-A*100000-B*10000-C*1000-D*100)/10);

var D = Mat[3];

var F = Math.integer(Matricula-A*100000-B*10000-C*1000-D*100-E*10);

var E = Mat[4];

var F = Mat[5];

4) In Plogue Bidule, which module do you use for splitting a mono signal in two, containing respectively low frequencies / high frequencies ?

o  Spectral / CrossFader

o  Mixing / Cross Fader

o  Mixing / Fader Cross

o  Building Blocks / Mixing / CrossFader

o  Building Blocks / Filters / Crossover Filter

5) In Plogue Bidule, how do you assign the number of inputs and outputs to a group object?

[]  Right click on group object, Group, and select “Properties”

[]  Right click on group object, Group, and select “Parameters”

[]  Select the objects to be grouped, right-click, Group, Group selected objects

[]  Connect the required inputs and outputs onto the corresponding outputs and inputs of the audio device

[]  It is automatically defined by the number of inputs and outputs of the first and last object in the group

6) Did you perform the home activity (Javascript class on Codacademy)?

7) Did you complete the Plogue Bidule equalizer exercise in class?
