8. Which units are generally involved in Multiply and Accumulate (MAC)? a. Adder b. Multiplier c. Accumulator d. All of the above 9. The type of systems which are characterized by input and the output quantized at certain levels are called as a. analog >AA b. discrete c. continuous d. digital 10. Should real time instruments like oscilloscopes be time invariant? a. Yes b. Sometimes c. Never d. They have no relation with timc variance D11. A system is said to be defined as non causal, whern a. the output at the present depends on the input at a earlier time b. the output at the prcsent does not depend on the factor of tin c. the output at the present depends on the input at the current time d. the output at the present depends on the input at a time instant in the future- 12. All causal systems must have the componcnt of a. memory b. time invariance c. stability d. linearity A 13.
