A first-order low-pass instrument has a time constant of 20 ms. Find the maximal sinusoidal input frequency that will keep output error due to frequency response less than 5%. Find the phase angle at this frequency

a) 262 Hz

b) 18.2°

Explanation:

a) The maximal sinusoidal  input frequency is given by:

The magnitude that will keep the output error less than 5% is 95% of its DC value = 0.95K. hence |H(jw)| = 0.95K, τ = 20 ms = 0.02 s

b)

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
