\[ A = 11 \]
Site na nsonaazụ dị n'elu, uru nke amplifier ọrụ a na-anaghị agbanwe agbanwe bụ ugboro iri na otu.
3. Ajụjụ Ihe atụ: Sistemụ Dijitalụ nwere Lotiri Mgbaàmà
Ajụjụ:
Ihe mgbaàmà dijitalụ nke nwere ụkwụ ise na-emepụta ụkpụrụ koodu abụọ 01101. Gbakọọ uru desimal kwekọrọ na ụkpụrụ koodu abụọ.
Azịza:
Iji gbanwee koodu binary ka ọ bụrụ decimal, anyị nwere ike iji usoro mmụba site na ike nke ụzọ abụọ. A na-amụba ọnụọgụ abụọ ọ bụla site na 2, bulie ya gaa na ike kwekọrọ na ọnọdụ ya site n'aka nri gaa n'aka ekpe, malite na ike nke 0.
Enwere ike ịgbakọ ụkpụrụ abụọ 01101 dị ka:
\[ 0 \ugboro 2^4 + 1 \ugboro 2^3 + 1 \ugboro 2^2 + 0 \ugboro 2^1 + 1 \ugboro 2^0 \]
Bụrụ:
\[ 0 \ugboro 16 + 1 \ugboro 8 + 1 \ugboro 4 + 0 \ugboro 2 + 1 \ugboro 1 \]
\[ = 0 + 8 + 4 + 0 + 1 \]
\[ = 13 \]
Ya mere, uru nke usoro ọnụọgụ abụọ 01101 bụ 13.
4. Ajụjụ Ihe atụ: Sekit Rectifier Full Wave
Ajụjụ:
Site na iji transformer steepụ nke na-ebelata voltaji site na 240V AC ruo 24V AC, ejikọtara na rectifier zuru oke, gbakọọ voltaji DC nke na-esi na ya pụta ma ọ bụrụ na diode ahụ dị mma (na-enweghị mbelata voltaji).
Azịza:
Ihe na-agbanwe ọkụ eletrik zuru oke na-agbanwe ọkụ eletrik AC ka ọ bụrụ DC site na idozi okirikiri AC dum. Enwere ike ịchọpụta voltaji DC nke ihe na-agbanwe ọkụ eletrik zuru oke mepụtara site na ịgbakọ voltaji nkezi nke ụdị ebili mmiri a gbaziri agbazi.
Maka diode na voltaji RMS zuru oke na ntinye (transformer mmepụta), voltaji DC mmepụta nke rectifier zuru oke nke na-agbanwe agbanwe bụ:
\[V_{DC} \approx \frac{2V_{RMS}}{\pi} \]
N'ebe a, voltaji RMS bụ 24V.
\[V_{DC} \ihe dị ka \frac{2 \u24}{3.14} \]
