What computer programme could I use to draw an accurate sinusoidal waveform giving the amplitude and the..?

Question

frequency of a signal? It's preferable to have a graph like what you get from an oscilloscope!

Answer 1

Try CAD programmes like AutoCAD, MicroCAD or the likes.

I'm assuming that you have the frequency and amplitude readings available to plot on the graph. If so, it's a simple matter of setting up the grid on CAD, and just using splines to join the points together.

Answer 2

since a sine wave is generated from a rotating generator why not use the same method to get your sine wave.
firstly draw a circle on paper, it's diameter will be the amplitude.
draw a long horizontal line through the centre of the circle to the right and, using a ruler, mark the line at small regular intervals. when the line is marked, using a ruler, make a vertical line at each mark, going upwards and downwards past the size of the circle.
next divide the circle along it's circumfrence into sixty parts, like the minutes on a clock face.
starting at the 12 o'clock position, draw a light horizontal line to the right, stopping at the first upward line on the first mark on the line.
once this is done, go to minute mark 1 and draw the light line and stop at the second upward line. do not worry if the lines nearly meet as this is normal.
do this for every mark on the circle and a perfect sine wave will be produced on the upward lines where the line through the centre will represent time. i have done this many times and it does work.

Answer 3

CAD program

Answer 4

"geometry expressions" might work for you....
they have a shareware version.
