Which of the following statements regarding binary counters are correct? (a) Clock inputs of all the flip - flops of a synchronous counter are applied from the same source whereas those in an asynchronous counter are from different sources. (b) The asynchronous counter has ripple effects whereas the synchronous counter does not. (c) Only J-K flip-flops can be used in synchronous counters whereas asynchronous counters can be designed with any kind of flip flops. (d) Latches can be used for designing asynchronous counters. Code :
A 12 MHz clock frequency is applied to a cascaded counter containing a modulus-5 counter, a modulus-8 counter, and a modulus-10 counter. The lowest output frequency possible is ________
In a 3-bit asynchronous down counter, at the first negative transition of the clock, the counter content becomes ____________
Workmen arrive at a mine workshop to receive tools for maintenance. The inter-arrival time of workmen at the service counter is exponentially distributed with an average time of 10 min. The service time at the counter is also distributed exponentially with a mean time of 6 min. The probability that there is a queue (more than one workman) at the service counter is,

Mark the incorrect proposition:
1. Set-off is a statutory defence to a plaintiff's action, whereas a counterclaim is a cross-action.
2. Set-off and counter-claim arises out of the same transaction.
3. Set-off should not be barred on the date of the suit while counter-claim should not be barred on the date of filing of written statement.
4. Claim for set-off cannot exceed plaintiff's claim, whereas counterclaim can exceed the plaintiffs claim.
5. Both set-off and counter-claim cannot exceed the pecuniary jurisdiction of the court.
Propositions are:
1. Set-off and counter-claim arises out of the same transaction.
2. Set-off should not be barred on the date of the suit while counter-claim should not be barred on the date of filing of written statement.
3. Claim for set-off cannot exceed plaintiff's claim, whereas counter-claim can exceed the plaintiff's claim.

Consider the following statement(s).
1. A defendant may set up, by way of a counter-claim against the claim of the plaintiff any right or claim in respect of the cause of action accruing to him.
2. The counter-claim may be submitted by the defendant even after he has delivered his defence.
3. The counter-claim shall not exceed the pecuniary jurisdiction of the court.
Which of the statements given above are correct?
Statement (I): The count-up overflow (OV) bit is 1 when the up-counter increments above the maximum positive value. Statement (II): The count-down underflow (UN) bit is 1 when the counter decrements below the minimum negative value.
