Digital circuit workflow: “In digital electronic systems, information is first converted into a coded group of pulses.” Assess this statement.

Introduction / Context:
Whether capturing sensor readings, key presses, or network packets, digital systems operate on coded binary representations. Before storage or computation, inputs must be represented as sequences of binary states (pulses) that the hardware can process.

Given Data / Assumptions:

• Input sources may be analog (sensors) or already digital (switches, digital interfaces).
• Processing units (CPU, MCU, FPGA, ASIC) operate on binary codes.
• Storage (RAM/flash) and communication links likewise use binary encoding.

Concept / Approach:
Analog sources pass through front-end conditioning and an ADC to become digital codes. Native digital sources already present coded pulses. In either case, usable information is encoded into time-ordered HIGH/LOW levels representing words, fields, and protocols.

Step-by-Step Solution:

Verification / Alternative check:
Observe any logic analyzer capture: information is present as sequences of logic states organized by timing/clocking conventions.

Why Other Options Are Wrong:
Incorrect: Opposes the very basis of digital processing.

“Only for microcontrollers/FPGAs” or “only for parallel/serial” improperly narrows a universal fact about digital systems.

Common Pitfalls:
Assuming that “pulses” imply only clocked parallel buses; serial links and asynchronous protocols also encode information into HIGH/LOW sequences.

Final Answer:
Correct
