Square waves are particularly useful in electronics as they can represent low and high states Square waves are particularly useful in electronics as they can represent low and high states

$($they only have $2$ states$).$ We can also create audio forms with square waves. Like any periodic

waveform, square waves will have an amplitude and frequency. Below is an example of a square

wave.

In WAVE files, this square wave can be represented using the minimum and maximum values of

bit depth, i$.$e$.$ in a WAVE file with a bit depth of $16,$ high states will be represented with the

number $32767$ and low states will be represented with the number $-32768.$

Write a MIPS program, called question$4.$asm, that will generate square waves. You will need to

obtain, from the user $($in this order$),$ the full output file name $($the entire path$),$ the tone

frequency $($how many times a wave period will appear within a second, an integer$),$ the sample

frequency $($how many sound samples will be measured in a second, an integer$),$ and the length

of the tone $($an integer in seconds$).$

Your output file should have $1$ channel only and a bit depth of $16.$ You should ignore the

contents of the header: set all $44$ bytes of the header to $0.$ Your tone should always start with the

high state. You may assume that the tone frequency, sample frequency and length will be such

that there will always be an even number of samples per wave period.

Note: for this question, the Automarker will not check your console output $($and there should not

be console output, only input$).$ It will only check your output file. When it prints your output file,

it will convert your binary file to a textual hexadecimal form.

Sample Console Input $($do not place the comments in the program

input$)$:

$/$home$/$lynn$/$Documents$/$CSC$2002$S$/$assign$1/$q$4\_$t$1\_$out.wav

$2$ # tone frequency

$20$ # sample frequency

$1$ # length of the tone
