Voltage to Frequency & Frequency to Voltage Conversion: Working and Applications
Voltage to Frequency (V/F) और Frequency to Voltage (F/V) Conversion इलेक्ट्रॉनिक सिस्टम्स में एक महत्वपूर्ण भूमिका निभाते हैं। इनका उपयोग मुख्य रूप से Signal Processing, Measurement Systems, और Industrial Control Applications में किया जाता है।
1. Voltage to Frequency (V/F) Conversion
Voltage to Frequency Converter (VFC) एक ऐसा सर्किट होता है, जो Input Analog Voltage को Proportional Frequency Signal में बदल देता है। यह Converters आमतौर पर ADC (Analog to Digital Conversion) और Remote Sensing Applications में उपयोग किए जाते हैं।
- Working Principle: VFC में एक Comparator, Integrator और Oscillator का उपयोग किया जाता है, जो Input Voltage के अनुसार Output Frequency को नियंत्रित करता है।
- Applications:
- Industrial Process Control
- Data Acquisition Systems
- Remote Telemetry
- Frequency Modulated Communication Systems
2. Frequency to Voltage (F/V) Conversion
Frequency to Voltage Converter (FVC) एक सर्किट होता है, जो Input Frequency को Proportional Voltage में बदलता है। यह Sensors, Motor Speed Control, और Power Monitoring Systems में प्रयोग किया जाता है।
- Working Principle: FVC में एक Frequency-to-Pulse Converter और Low-Pass Filter का उपयोग किया जाता है, जो Output Frequency को एक Smooth Voltage Signal में बदलता है।
- Applications:
- Speed Measurement in Tachometers
- Digital-to-Analog Conversion in Communication Systems
- Power Line Frequency Monitoring
- Automatic Gain Control (AGC) Circuits
