FAQ:

Q: What can you do with a digital signal generator?

A: It can be used to generate test signals for audio amplifiers, PWM signals for MOSFET or transistor circuits,generate clock signals for digital circuits,and this list goes on…. In this instructable lets build one on our own.

Q: How to vary the output frequency of the signal generator?

A: For example: if S1 is at X10 position and R1 is varied over the full range, then the out frequency from signal generator is from 10Hz to 100Hz. Similarly if the switch is at X100, then the output frequency is from 100 Hz to 1000Hz. Vary the 5 Kohm Pot connected to the op-amp and can be used to vary the signal amplitude.

Q: What is an RF signal generator?

A: The RF signal generator is a must to have tool when playing with radio receivers. It is used to tune a resonant circuits and adjust the gain of different RF stages. Very useful feature of the RF Signal generator is its modulation capability.

Q: How to select the type of signal and frequency range?

A: The DIP switches can be used to select the type of signal and the frequency range. For example: if S1 is at X10 position and R1 is varied over the full range, then the out frequency from signal generator is from 10Hz to 100Hz.
