Circuit 156:
LF phase shifter 180°
Setup information
Install the transistor, the six resistors and the three electrolytic capacitors as shown in Fig. 2.156. The nine
jumper wires come next. Check the placement on the board again and only then connect the battery.

LF phase shifter
180 degrees
Experiment
Our circuit here will delay the passage of LF signals causing a phase shift of about 180°. When this signal
is mixed with the original signal, we have got the well-known Phaser Effect, which can be increased until it
completely exits the phase.
The circuit diagram for this experiment is shown in Chap. 3, Fig. 3.156.
