Question
A 4-bit ADC converter has a full-scale analog imput of 5
Volt. Its resolution is _________Solution
Resolution of an ADC is the smallest change in analog input that can be detected and represented as a change in the digital output code. It depends on the number of bits (n) of the ADC. More bits → finer steps → higher accuracy.

Find the value of sin(θ) if 2sinθ = tanθ, for 0 < θ < 90°.
Simplify the following trigonometric expression:Â
