In TTL (Transistor-Transistor Logic) circuits, resistance and propagation delay are inversely related. Higher resistance in the circuit can lead to increased propagation delay, as it affects the charging and discharging times of capacitive loads. This delay is primarily due to the time it takes for the output to transition from one state to another, which is influenced by the RC time constant (where R is resistance and C is capacitance). Thus, optimizing resistance is crucial for improving speed in TTL logic applications.

What is the figure of merit of logic family?
A figure of merit correlated with the energyefficiency of a device. It can be calculated by the product of propagation delay time with power dissipation.

Explain how propagation delay affects the speed of modern PCs?
A: I wouldn't call propagation delay that applies to other media. for a PC delay are parasitic in nature mostly layout. But the real and actual delay is inherited from the I/O which is the soul of PC speed. No matter how fast a PC is internally it must service those interrupts and that is really the delay actually
Which logic family has the least propagation delay?
Here are the propagation delays for these gatesa) ECL = 2nsb) TTL = 1.5-33ns depending on the type of TTL. Conventional TTL is 9ns, Advanced Schottky TTL is 1.5nsc) RTL = 25nsd) CMOS = 5-20ns depending on if it is conventional CMOS, TTL pin compatible CMOS, high speed TPC CMOS or TTL compatible CMOSSo the fastest would be the Advanced Schottky TTL (74ASxx) at 1.5ns but the choice simply said TTL which I would interpret as Conventional TTL (74xx/54xx) which would have a propagation delay at 9ns.So the winner is ... (a) ECL which has a propagation delay at 2ns.
What causes packet delay?
Packet delay is caused by several factors, including propagation delay, transmission delay, queuing delay, and processing delay. Propagation delay occurs as packets travel through the medium, while transmission delay is the time taken to push all packet bits onto the network. Queuing delay happens when packets wait in line at routers or switches due to network congestion, and processing delay is the time taken by devices to process the packet headers and make forwarding decisions. Each of these factors can contribute to the overall delay experienced in data transmission.
