wave pulses

electronic signal

binary code

electromagnetic signals

a pulse of information sent as a pattern in a controlled flow of current through a circuit

information sent as patterns in the form of electromagnetic waves, such as radio waves

a pulse of energy that travels through the circuit when it is closed

digital signals are continuous

analog signals are higher resolution

digital signals can be better stored electronically

analog signals consist of numerical values recored at a specific time interval

digital signals take up more space

lower the amplitude of the analog signal

raise the amplitude of the analog signal

lower the sampling rate of the analog signal

raise the sampling rate of the analog signal

bytes and digits

analog and digital

dots and dashes

pixels and bits
