What is difference between RF and IF?

What is difference between RF and IF? RF to IF conversion is achieved using a RF device called Down-converter. Heterodyne and homodyne receiver architectures are used to convert modulated RF signal to IF signal. Superheterodyne uses 10.7MHz as first IF and 470KHz as second IF….RF vs IF. Type of application Intermediate Frequency value Radar 30MHz […]

Does Bubble Wrap actually work?

Does Bubble Wrap actually work? Ms Edwards said the bubble wrap should also cover the metal window frames, which are “really conductive”. She said many houses in the ACT were poorly insulated. Bubble wrap works by increasing the isolative value of the window, making it effective in keeping the heat out in summer and preventing […]

What is the slowest spreading ocean?

What is the slowest spreading ocean? The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end. What is the difference between a fast spread and a slow spread? Steep steps in the seafloor that can […]

What can charge an insulator?

What can charge an insulator? A conductor is a substance that allows charge to flow freely through its atomic structure. An insulator holds charge within its atomic structure. Objects with like charges repel each other, while those with unlike charges attract each other. What is difference between conduction and induction? In conduction, the neutral body […]

What is the fastest accelerating plane?

What is the fastest accelerating plane? Lockheed SR-71 Blackbird What is the highest Mach speed ever recorded? It’s Official. Guinness World Records recognized NASA’s X-43A scramjet with a new world speed record for a jet-powered aircraft – Mach 9.6, or nearly 7,000 mph.

Which orbitals Cannot form a pi bond?

Which orbitals Cannot form a pi bond? dx2−y2+py sideways overlapping does not form π-bond as the two orbitals do not have proper orientation for the overlap. Was this answer helpful? Can pi bonds be formed in absence of sigma bonds? Yes, there exists pi bonds without coexisting sigma bonds. Here both the bonds of the […]

Where is productive efficiency?

Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]
