Q1:

Which of the following is true in a tape recorder?

A Vow is due to variation in motor speed but flutter is due to some other reason

B Both vow and flutter are due to variations in motor speed

C Flutter is due to variation in motor speed but vow is due to some other reason

D Neither vow nor flutter is due to variation in motor speed

ANS:B - Both vow and flutter are due to variations in motor speed

Small variation (less than 6%) in motor speed causes vow and large variation (more than 6%) in motor speed causes flutter.
