A complete schematic diagram of the voice disguiser is presented. Microphone MIC1 captures the voice signal and transmits it to an audio amplifier, which consists of Q1 and Q2, along with several supporting components. This amplifier features a low-pass...
A field effect transistor amplifier features a fixed bias input source with feedback, resulting in very high input impedance and low capacitance. It drives a field effect transistor or emitter follower, despite having a very low output impedance, utilizing...
The automatic anti-frost crop controller circuit comprises an electric contact mercury thermometer (Q), a control circuit, ignition devices, and other components. The electric contact mercury thermometer features two platinum electrodes; one acts as a contact electrode inserted at the...
The attenuation circuit is a feedback tone control system that consists of transistors and an RC network. The circuit includes a low tone control potentiometer (RP2) and a treble control potentiometer (RP3). The bass control is influenced by resistor...
This picture and schematic were intended for posting on my Watson's blog, but it did not get published. The circuit schematic in question likely includes various electronic components arranged to perform a specific function. Typically, such schematics are used to...
A binary gain step circuit is illustrated using the PGA205, which has a gain range of 1 to 64. The circuit employs two PGA205 devices in cascade, resulting in a total gain that is the product of the individual...
