इंग्रजी मध्ये PRESELECTOR म्हणजे काय?
प्रेस्लीक्टर
इतर उपयोगांसाठी, प्रिस्लेक्लर पहा. प्रिसेलेटर हा इलेक्ट्रॉनिक उपकरणांसाठी एक रेडिओ तांत्रिक संज्ञा आहे जो ऍन्टीना आणि रिसीव्हर दरम्यान लावण्यात आला आहे, त्यास लागू होणाऱ्या फ्रिक्वेन्सीच्या श्रेणी मर्यादित करणे. इच्छित वारंवारतेवर ट्यूनिंग प्रेक्षकांच्या अरुंद बँडविड्थला ऑपरेटिंग वारंवारतेवर केंद्रित करते, आउट-ऑफ-बैंड अवांछित हस्तक्षेप सिग्नल नाकारताना किंवा कमी करते. याव्यतिरिक्त एक प्रेक्लटर संवेदनशील रिसीव्हर इनपुटला स्थीर आणि व्होल्टेज क्षणिक आणि जवळपासच्या ट्रान्समिटर्सकडून मजबूत सिग्नलद्वारे झालेल्या नुकसानापासून संरक्षण करू शकतो. हे जवळजवळ कोणत्याही प्राप्तकर्त्याचे कार्यप्रदर्शन सुधारते परंतु विशेषत: ब्रॉडबँड फ्रंट-सिम्स असणा-या लोकांसाठी विशेषतः उपयोगी आहे जे ओव्हरलोडसाठी प्रवण असतात, जसे की स्कॅनर किंवा सरासरी रिसीव्हर अतिरिक्त फिल्टरिंग आवश्यक आहे कारण RF पावर एम्पलीफायर आणि मिक्सरच्या इच्छेनुसार रिसीव्हर्सच्या समोर मर्यादित गतिशील श्रेणी आहे. त्या सर्किट्सवर ओव्हरलोडिंग न करता हाताळू शकत असलेल्या आरएफ एनर्जीची मर्यादा आहे. फ्रंट-एंड ओव्हरलोड म्हणून, प्राप्तकर्त्याची कार्यक्षमता कठोरपणे कमी होते किंवा अगदी खराब होते.
