Audio data: The two lines represent the 20 bit audio word for both<br />

channels.<br />

• LSB on the left side, least significant bit<br />

• MSB on the right side, most significant bit<br />

The right bits always have to be active. In case some of the left bits<br />

are constantly 0, the resolution of the audio signal is obviously less<br />

than the maximum of 24 bits (including the aux. bits). The number<br />

of arrows from right to left may be counted to find the actual word<br />

length or binary resolution.<br />

Application hints:<br />

Measurement Functions<br />

• Any digital input signal causes that some of the MSB’s are<br />

active. The <strong>Digilyzer</strong> counts the number of active bits and<br />

displays the result as actual word length.<br />

• Sometimes bits of the input signal are stucked on “0“ or “1“.<br />

In such a case a device in the signal chain is defective, e.g.<br />

a receiver or a transmitter.<br />
