# Industrial Specification: Decoding Circuit

## 1. Technical Definition
Electronic circuit that processes and interprets barcode signals into readable data.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 V DC input voltage, -20°C to +85°C ambient temperature, 0-1000 lux illumination**. Failure boundary: **Input voltage below 2.7 V or above 5.5 V causes signal distortion; ambient temperature exceeding 125°C triggers thermal shutdown; illumination below 50 lux reduces signal-to-noise ratio by 15 dB**, Mechanism: **Semiconductor junction breakdown at 5.5 V due to avalanche multiplication; thermal runaway above 125°C from increased leakage current (doubling every 10°C per Arrhenius equation); photodiode quantum efficiency drops below 30% at 50 lux**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
