🔍 Key Concepts

• SINAD (Signal + Noise And Distortion) measurement and what is actually being measured at the meter terminals • How a 1 kHz test tone is treated so that only noise and distortion remain for measurement • Difference between bandpass, bandstop (notch), highpass, and lowpass filters at 1000 Hz

💭 Think About

• Ask yourself: in a SINAD test, do we want the meter to read mainly the clean 1000 Hz tone, or the unwanted noise and distortion components after that tone is removed? • Which type of filter at 1000 Hz would REMOVE a strong 1000 Hz test tone but let nearby noise and distortion components be measured? • Why would decibels be a more useful scale than millivolts when comparing signal quality (SINAD ratios) across different receivers and levels?

✅ Before You Answer

• Identify which option uses a filter centered at 1000 Hz that would mostly REMOVE that 1000 Hz tone from the measurement. • Verify which filter description matches a notch (bandstop) behavior versus a bandpass, highpass, or lowpass behavior at 1000 Hz. • Decide whether a SINAD reading is more commonly expressed in dB or in absolute voltage (millivolts) when specifying receiver performance.
