Lab SSB Detection System uses product detection method, which includes JFET, which operates on the depletion mode. That has the IF signal applied to the gate through an LC tuned circuit formed by L1 and C3, C4. The carrier signal is generated by a Beat Frequency Oscillator and inserted on the source through the LC tuned circuit of L2 and C1, C2. The circuit operates similar to mixer and is biased to provide the peak value composite signal required to detect and recover the base band signal. The entire detection circuit is printed on the multi-coloured front panel for the students to understand early. Spring terminals are provided for interconnection. Trainer comes with multi-coloured front panel PCB designed with the aid of C.A.D. Trainer comes with built-in DC regulated power supply. HOUSING: Trainer comes with FRP sloping metal cabinet for letter better viewing. DIMENSION: 27cms x 17cms x 10cms (app.) WEIGHT: 1kg (app.) POWER: 230V AC, 50Hz mains operated. Trainer comes with built-in DC regulated power supply. |
