PSW Staff 06/11/09 08:11 AM, 0 CommentsThis calculation will give you the ratio, in decibels, between two voltages. For example, you can calculate the gain needed to raise the output level from 0.775 volts to 1.4 volts. You can also use this to calculate how much attenuation you need if, for instance, you have a 2.0 volt input level and you need to attenuate it to 0.2 volts to prevent input overload. Enter any two values and press “Calculate” for the remaining value. Press “Reset” before… View this story

The choices typically available in the calculators are as follows. Pink Noise: Duty cycle of 50%. Dance: Duty cycle of 40%. Typically highly-compressed, low-frequency material at very high levels. Hard Rock: Duty cycle of 30%. Full-range, continuous rock music at concert levels. BGM: Duty cycle of 20%. Background music, typically used in business music applications at low… View this story
