# Signal Processing Analysis

**Discipline**: Signal Processing | **Tools Used**: 4 | **Servers**: 3

## Description

Analyze signals: duty cycle, frequency range, electron wavelength, and measurement error analysis.

## Tools Used

- **`calculate_duty_cycle`** from `server-21` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/21/Electrical_Engineering_and_Circuit_Calculations`
- **`calculate_frequency_range`** from `server-23` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/23/Optics_and_Electromagnetics`
- **`electron_wavelength`** from `server-23` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/23/Optics_and_Electromagnetics`
- **`calculate_absolute_error`** from `server-26` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/26/Data_processing_and_statistical_analysis`

## Workflow

1. Calculate duty cycle
2. Calculate frequency range
3. Compute electron wavelength
4. Analyze measurement error

## Test Case

### Input
```json
{
    "pulse_width": 0.005,
    "period": 0.02
}
```

### Expected Steps
1. Calculate duty cycle
2. Calculate frequency range
3. Compute electron wavelength
4. Analyze measurement error

## Usage Example

> **Note:** Replace `sk-[REDACTED]` with your own SCP Hub API Key. You can obtain one from the [SCP Platform](https://scphub.intern-ai.org.cn).

```python
import asyncio
import json
from contextlib import AsyncExitStack

    "server-23": "https://scp.intern-ai.org.cn/api/v1/mcp/23/Optics_and_Electromagnetics",
    "server-26": "https://scp.intern-ai.org.cn/api/v1/mcp/26/Data_processing_and_statistical_analysis"
}

async def connect(url, stack):
    transport = streamablehttp_client(url=url, headers={"SCP-HUB-API-KEY": "sk-[REDACTED]"})
    read, write, _ = await stack.enter_async_context(transport)
    ctx = ClientSession(read, write)
    session = await stack.enter_async_context(ctx)
    await session.initialize()

                try: return json.loads(c.text)

        data_2 = parse(result_2)
        print(f"Step 2 result: {json.dumps(data_2, indent=2, ensure_ascii=False)[:500]}")

        # Step 3: Compute electron wavelength
        result_3 = await sessions["server-23"].call_tool("electron_wavelength", arguments={})
