The LED in Figure below requires 30 mA to emit a sufficient level of light. Therefore, the collector current should be approximately 30 mA. For the following circuit values, determine the amplitude of the square wave input voltage necessary to make sure that the transistor saturates. Use double the minimum value of base current as a safety margin to ensure saturation. VCC = 8 V, VCE(sat) = 0.3 V, RC = 200 Ω , RB = 3.3 kΩ , b (beta) = 45, and VLED = 1.6 V
