The difference between latches and flip flops is shown

Latches

Flip Flops

Latches are building block of sequential circuits and they are built using logic gates

Flip flops are also building blocks of sequential circuits but they are made using latches

Latches continuously change the input and output changes correspondingly

Flip flop output changes only when a clock is applied

Latches are level sensitive

Flip flops are edge sensitive

Statement: Kalyan Jewellers has chalked out an aggressive expansion plan to double its retail stores to 250 in India and abroad as well as the turnover to Rs. 25,000 crore over the next five years.The Kerala-based jeweller currently operates 100 stores in the country and 32 overseas with a turnover of Rs. 10,500 crore in the 2017-18 fiscal year. Courses of action: I. The company is targeting to reach 250 stores in the next five years and investments will be met through internal accruals.  II. The company is expanding its retail network aggressively. In this fiscal, it earmarked Rs. 1,000 crore to open new stores. Already, Rs. 600 crore has been spent to launch 10 stores in the first of this fiscal and the remaining Rs. 400 crore will go towards adding 9-10 more stores by March 2019. III. The company is ‘hyper-local’ in nature and jewellery designs sold in each store keeps in mind the taste and traditions of the local region.

An FH binary orthogonal FSK system employs an m 15 stage liner feedback shift register that generates an ML sequence. Each state of the shift register selects one of L non over lapping frequency bands in the hopping pattern. The bit rate is 100 bits/s. The demodulator employ non coherent detection. Suppose the hop rate is increased to 2 hops/bit and the receiver uses square law combining the signal over two hops. The hopping bandwidth for this channel is?

Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   Consider the following digital circuits. 1. Multiplexers 2. Read Only Memories 3. D-latch 4. Circuit as shown in figure below Which of these come under the class of combinational circuits?
