455 kHz IF Amplifier Frequency Response Measurement + Easy Excel Method

#IFAmplifier #455kHz #FrequencyResponse 📡 455 kHz IF Amplifier – Complete Frequency Response Measurement If you haven’t seen the first part yet, make sure to check it out — it gives the full background of the IF amplifier project. 👉 YouTube link:    • Transistor IF Amplifier for Radio Projects   In this video, I test the frequency response of my 455 kHz transistor IF amplifier. First we measure the gain and basic operation, then we move to a detailed frequency-domain analysis using FFT and a tracking generator. Finally, I show a simple method to measure the frequency response even without a spectrum analyzer — using nothing more than a basic oscilloscope and an Excel table. This technique is very useful if you want to characterize IF filters, amplifier stages, or other narrow-band RF circuits. 🔧 Topics covered Basic gain test at 455 kHz Setting up FFT and sweep mode Finding peak frequency and −3 dB bandwidth Examining filter asymmetry Measuring bandwidth using X- and Y-axis cursors Manual frequency response measurement using a simple oscilloscope Building a frequency–amplitude table in Excel Plotting the response curve and evaluating the result 📌 Why this video is useful Works with low-cost test equipment Shows both “professional” and “budget” measurement methods Ideal for hobby radio builders, IF filter designers, and RF learners 🎥 Watch my other videos: DIY Mini Class-AB Amplifier for Headphones & Radio Output | Live Tests + PCB →    • DIY Mini Class-AB Amplifier for Headphones...   Colpitts Oscillator Experiment #2 – Live BFO Test and SSB Reception →    • Colpitts Oscillator Experiment #2 – Live B...   Hartley Oscillator – Radio Local Oscillator Build & Simulation →    • Hartley Oscillator – Radio Local Oscillato...   #IFAmplifier #455kHz #FrequencyResponse #RFAmplifier #RadioElectronics #RFmaker #ElectronicsDIY #IFStage #SSBReceiver #Oscilloscope #ExcelTrick #ElectronicsMeasurement #RFTesting
