Question 1 of 27070

Q

What kind of input signal could be used to test the amplitude linearity of a single-sideband phone transmitter while viewing the output on an oscilloscope?

🔍 Key Concepts

• Single-sideband (SSB) modulation behavior with different audio inputs • How amplitude linearity is checked using test tones • The difference between single-tone and two-tone testing for RF amplifiers and SSB transmitters

💭 Think About

• Which type of audio signal will produce a clearly defined, repeatable pattern on an oscilloscope, making it easy to see distortion? • How does using one tone vs two tones affect your ability to see whether the transmitter is compressing or clipping the signal? • Which waveform is normally used in radio practice to check linearity of SSB stages and intermodulation distortion?

✅ Before You Answer

• Make sure the signal is stable, repeatable, and not voice-dependent • Confirm that the test signal will exercise the SSB transmitter over a range of amplitudes, not just a single level • Check which option is commonly specified in radio/SSB test procedures for checking linearity and intermodulation products
