Signal generator

What you're looking at: the screen plots one signal, x(t), over a short slice of time. The horizontal axis is time in milliseconds and the vertical axis is the signal's value. The amber bracket marks one period, the time a single cycle takes. Every number below is measured from the plotted signal itself.

Phase slides the wave along the time axis. You can't hear it on a single tone; it matters when waves are combined.

Time window

Live synthesis, starts quiet

Frequency f: cycles per second: 220 Hz
Period T = 1/f: time for one cycle: 4.55 ms
Phase φ: shift along the cycle: 0° = 0.00 rad
Peak: largest distance from zero: 0.800
Peak-to-peak: highest minus lowest: 1.600
RMS: root-mean-square: a measure of average strength: 0.566

x(t) = A\,\sin(2\pi f t + \varphi)

x(t) = 0.80\,\sin(2\pi \cdot 220\,t)

$x(t)$: the signal's value at time t
$A$: amplitude, the peak height
$f$: frequency, in cycles per second (Hz)
$t$: time, in seconds
$\varphi$: phase, in radians (360° = 2π rad)

Predict first

If you double the frequency, what happens to the period T, the time one cycle takes?
