Single Stage Transistor Amplifier is designed to observe voltage and current gain of a single stage transistor amplifier, to plot frequency response curve and to measure input and output impedance of a single stage transistor amplifier. The Amplifier has built-in 9V DC power supply for proper biasing. The Amplifier has the feature that circuit diagram is well engraved on the front panel with terminals provided for connecting signal generator and oscilloscope. The Single Stage Transistor Amplifier has circuit mounted on the back side of the front panel.
