How to calculate power dissipation in TTL circuits

Find the input thermal noise voltage of a receiver with a bandwidth of 3.33 kHz, with an input resistance of 42 Ω, and a temperature of 29oC.

Assuming that an oscilloscope displays a V_max of 5.22V and V_min of 1.33V. Calculate the percentage of modulation. (5 points)

Given the signal power of 2.3μw and the noise power of 0.7μw, calculate the signal-to-noise-ratio.

It has been estimated that there are about 1029 free electrons per cubic meter in

copper. Find the average drift velocity (in units of meters per hour) of electrons in a 1.0

mm diameter copper wire carrying a 3A current. Start your clearly shown work from

the definition of current, that is the amount of charge passing a cross-section per unit

time

1. Three (3) AM broadcast stations are spaced at 18 kHz, beginning at 73 kHz. Each station is allowed to transmit modulating up to 6 kHz. Compute for the upper and lower sidebands of each station.
