Question

The energy stored in an inductor is: Select one: O a. 12LI2 b. 34C12 O c.44C12 O d. VLI What bit value (i = ?) will produce an output clock frequency of approximately 1000 Hz without going lower than 1000Hz. Assume an input clock frequency of 2 MHz. 0 Select one: a. 10 O b. 8 O c. 9.96 O d. 11 o e. 9 O f. 10.3215 0 0 What is the gain () of the amplifier below? 1747 W 5k2 ºs + W 40 k 2 20 kg Answer:

Answer 1

1.

ENERGY STORED IN A INDUCTOR = 1/2 LI2  (OPTION A IS CORRECT)

2.

SINCE

2x106/211 = 976.5625 hz

and

2x106/210 = 1953.125hz

and we can not go lower than 1000 hz

so option A is correct

(although 10.3215 will give lower frequency but we can not use it because bit value needs to be a positive natural number)

3.

voltage gain (v0/vi) = (-40/5)

= -8 (answer)

please give a thumbs up
