-Vee refers to the emitter bias voltage in a transistor amplifier circuit, which is typically negative in relation to ground. In this case, -Vee is specified as -12 V, indicating that the emitter is biased at 12 volts below ground potential. The circuit operates between +12 V and -12 V, with Vcc representing the positive collector bias voltage. Understanding the polarity of these voltages is crucial for proper circuit function. Clarification on these parameters is essential for effective amplifier design.
