A chopper may be thought as a O a. DC equivalent of an induction motor O b. DC equivalent of an AC transformer O c. Diode rectifier O d. Inverter with DC input

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

A multiplexer   a.Takes a single data input and routes it to one of several outputs b.Selects from many data sources c.converts a binary code input to a single output d.converts a single input to a binary code

5) Draw the circuit diagram using diode and write the truth table of a logic gates whose output will be the logical OR operation of two inputs.

b) Draw a fully labelled block diagram of a demodulator suitable for DSB-AM, DSB-SC, and SSB signals. Explain briefly it's operation, and why a simple diode detector would not have been suitable.
