A prolific author of technical articles and books, Christophe P. Basso (ON Semiconductor, Toulouse, France) has written a new book, Linear Circuit Transfer Functions—An Introduction to Fast Analytical ...
The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...
This bass and treble controller circuit is based on the classic Baxandall tone control circuitry and provides a maximum cut and boost of around 10dB at 10kHz and 50Hz. The first stage that is built ...
