Appreciate any help with the following electronics engineering questions, need within next few hours:
1) What is the value of the coefficient +0.1837 if it is quantized to 5 bits?
2) Given a sampling frequency of fs and an input signal of f1, which is greater than fs/2, how would the resulting aliased frequency, fa, be expressed?
3) What equation would correctly describe a sampled signal with values of 1 at n = 0, 1, 2, and 3 and 0 everywhere else?
4) A digital function is written as x[n] = δ[n] â 0.5δ[n â 2]. What is the equation if x[n] is delayed for two samples?
5) May be related to the analog frequency f0 by what mathematical relationship?
