voltops 0.2.0

A Python library for electronic formulas and signal processing

Voltops

Voltops is a Python library built for electronics and signal processing enthusiasts. Whether you're an engineer, student, or hobbyist, this package offers intuitive functions for working with electrical formulas and analyzing signals with ease. Every function is physics-aware—values carry metadata (DC/AC, RMS/peak, phase, frequency) so you catch mistakes before they propagate.

Installation

pip install voltops

Quick Start

Basic Electronic Formulas

from voltops.formulas.basic import BasicFormulas

# Calculate voltage using Ohm's Law: V = I * R
voltage = BasicFormulas.ohms_law(current=2, resistance=5)
print(f"Voltage: {voltage.value} V (kind={voltage.metadata.kind})")

# Calculate power: P = V * I
power = BasicFormulas.power(voltage=voltage, current=2)
print(f"Power: {power.value} W")

Frequency Spectrum Analysis

import numpy as np
from voltops.signal_processing.transforms import Transforms

# Generate a simple sine wave signal
t = np.linspace(0, 1, 1000, endpoint=False)
signal = np.sin(2 * np.pi * 10 * t)

# Get the frequency spectrum
freqs, amps = Transforms.frequency_spectrum(signal, sampling_rate=1000)

Filtering Signals

from voltops.signal_processing.filters import Filters

# Create a signal with multiple frequency components
t = np.linspace(0, 1, 1000, endpoint=False)
signal = np.sin(2 * np.pi * 10 * t) + 0.5 * np.sin(2 * np.pi * 20 * t)

# Apply a low-pass filter with a cutoff at 15 Hz
filtered_signal = Filters.low_pass_filter(signal, cutoff=15, sampling_rate=1000)

Features

• Physics-aware quantities: Voltage, Current, Resistance/Impedance, Power, Frequency, and Phase objects with waveform metadata.
• Electronic Formulas: Ohm's Law, power, and more—now returning safe quantity objects.
• Signal Processing: FFT, DFT, filtering, and spectral analysis.
• Extensible API: Easy-to-use, modular design for seamless integration.
