A standard oscillator circuit used for low to moderate frequencies in the range of 5 Hz to 1 MHz and the one almost always used in commercial audio generators is the ________.
A) Hartley
B) Armstrong
C) Wien-bridge
D) phase-shift

Question

Quizplus · Accepted Answer

The Wien-bridge oscillator is a type of RC oscillator that is commonly used for generating low to moderate frequency signals in the audio range (<20 kHz). It is known for its stability and low distortion output, making it a preferred choice for commercial audio generators. The Hartley and Armstrong oscillators are typically used at higher frequencies (>1 MHz), while the phase-shift oscillator is more commonly used at lower frequencies (<1 Hz).
