2.74 LF phase shifter
Circuit 154:
LF phase shifter 10°
Setup information
Install the two transistors, the six resistors and the three electrolytic capacitors as shown in Fig. 2.154. The
nine jumper wires come next. Check the placement on the board again and only then connect the battery.

Experiment
Our circuit here will delay the passage of LF signals causing a phase shift of about 10°. When this signal is
mixed with the original signal, we have got the well-known Phaser Effect.
The circuit diagram for this experiment is shown in Chap. 3, Fig. 3.154.
