Sounds can be characterized by _____________ waveforms.
frequency range for audible sound is between 20 and 20,000 Hz. When a
time varying waveform such as a pulse train of sufficient frequency and
amplitude is sent to a speaker, the speaker emits audible sound.
The 555 timer in an astable multivibrator circuit can be adjusted to
generate a _____________ .
_____________ can be adjusted by changing the values of the passive
elements in the circuit, i.e. the capacitor, and the two resistors.
The pulse width is the _____________ of time a signal remains high, and
the duty cycle is the ratio of the pulse width to the _____________ of the
waveform.
Aliasing is a phenomenon that occurs when the _____________ is less
than twice the frequency of the signal being sampled. This can cause
significant misinterpretations of the signal data.
Data can be conveniently stored and accessed in RAM using an
_____________ . The index of an array variable can be _____________
using a
indexed as bytes 0 through 9.
