Question 1

An uncompressed signal within the receiver of an ultrasound system has a dynamic range of 110 dB. The signal undergoes 40 dB of compression. What is the dynamic range of the compresses signal?

Answer 1

110dB-40dB=70dB

Question 2

An uncompressed signal has a dynamic range of 85 dB. The signal undergoes 30 dB of compression. What is the dynamic range of the original, uncompressed signal?

Answer 2

85dB-30dB=55dB

Question 3

After compression, a signal within the ultrasound system has a dynamic range of 70 dB. The original signal was compressed by 40 dB. What is the dynamic range of the original, uncompressed signal?

Answer 3

70dB+40dB=110 dB

Question 4

A signal within a system’s receiver has a dynamic range of 60 dB after compression. The original was compressed by 50 dB. What is the dynamic range of the original, uncompressed signal?

Answer 4

60 dB+50 dB=110 dB
