Sample and Hold Board

The Sample and Hold samples a source waveform at a set clock rate and outputs the voltage that was present at the the sample point. It holds that voltage level until the clock cycles.

The Sample and Hold contains an internal triangle Low Frequency Oscillator and an internal clock (a squre wave LFO). Either one can be substituted by applying an external signal to the appropriate external input jack.

The input jacks must be interrupting-type for the S/H to operate properly.

The clock output buffers and outputs either the internal or any external clock to the clock output. This allows for timing synchronization with other modules.

The LED's indicate the oscillator and clock rates being utilized, internal or external

The track and hold function allows the internal or external oscillator source to pass though to the output during 1/2 of the clock cycle. When the clock switches states from low to high, it samples the input source and holds the voltage sampled until the clock switches states and goes low again.
