In a full-wave rectifier _______________. a) the output is apure DC voltage. b) only the negative half of the input cycle is used. c) only the positive half of the input used. d) the complee input cycle is used.

For the circuit shown below, identify the logic function performed by it. Also determine the high level fan-out, if Rp(pull-up resistor) = 10 ks. Compute the maximum value of Rp for a fan-out of 5. Assume that input diode has a leakage current of 100 μA. Given: V₁ = 0.7V, V (forward voltage drop) = 0.8V, VBE(cut-in) = 0.5V, VCE(sat) = 0.2V. Transistor leakage current is negligible. 1H Ao- Во Co D₂ D 20 ΚΩ P₁ P₂ 10 kQ D₁ www 10 ΚΩ >+5V Rp Іон
