amplifier How does this circuit attenuate high frequencies
This circuit can function as a treble control circuit, with high-frequency gain occurring when resistor R3 is set to a value that makes points a and b equal (denoted as k=0). Conversely, high-frequency attenuation occurs when R3 is set to...
Tone Controls
The circuit operates from a 12V or similar power supply, with the option to adjust resistor R1 for higher voltage applications. There is significant flexibility in selecting values for components like capacitor C1. At point B, VR1 serves as a...
Spice and the art of preamplifier design
One of the main considerations in phono preamplifier design is the choice between active (feedback) and passive equalization. An ideal feedforward preamplifier for a moving magnet cartridge would provide approximately 40 dB of gain before the equalizer (more for low-output...
