1. Sinyal Analog vs Sinyal Digital

1.1 SinyalAnalog AnalogSignals

SinyalAnalog analogsignals adalahare sinyalsignals yangthat bersifatare kontinucontinuous — artinyameaning nilainyatheir dapatvalues berubahcan secarachange mulussmoothly tanpawithout lompatan,jumps, merepresentasikanrepresenting besaranphysical fisikquantities darifrom duniathe nyatareal sepertiworld suhu,such cahaya,as suara,temperature, danlight, tekanan.sound, and pressure.

KarakteristikCharacteristics sinyalof analog:analog signals:

• NilainyaValues dapatcan berupabe semua nilaiany real value dalamwithin suatua rentangrange.
• SensitifSensitive terhadapto noise (gangguanelectromagnetic elektromagnetik,interference, panas,heat, dll.etc.).
• BerinteraksiInteract langsungdirectly denganwith duniathe nyatareal world (sensor,sensors, mikrofon,microphones, fotodioda)photodiodes).

1.2 SinyalDigital DigitalSignals

SinyalDigital digitalsignals adalahare sinyalsignals yangthat bersifatare diskritdiscrete — nilainyatheir hanyavalues dapatcan berupaonly duabe kondisi:in two conditions: HIGH (1) atauor LOW (0), biasanyausually berbentukin the form of a square wave.

KarakteristikCharacteristics sinyalof digital:digital signals:

• HanyaOnly memilikihave duatwo nilaivalues: 0 danand 1 (LOW danand HIGH).
• HampirNearly kebalimmune terhadapto noise.
• DigunakanUsed dalam transmisiin data dantransmission pemrosesanand diprocessing dalamwithin perangkatelectronic elektronikdevices.
• MenggunakanUse energiless lebih sedikitenergy.
